Answer:
The height of the tree is approximately 71.5 feet
Step-by-step explanation:
The given parameters are;
The angle of elevation to see the top pf the tree = 50°
The distance Peggy is laying from the base of the tree = 50 ft.
In order to answer the question using trigonometric ratio, we assume that the angle the tree makes with the ground is 90° that is the tree is perpendicular to the ground
Therefore, the line of sight to the top of the tree, the height of the tree, and the distance from the base of the tree where Peggy is laying, forms a right triangle
Let, 's', represent the line of sight to the top of the tree, let 'h', represent the height of the tree, and let, 'd', represent the distance from the base of the tree where Peggy is laying
The third angle, θ, of the right triangle opposite 'd' is given by angle sum theorem of a triangle as follows;
θ = 180° - 90° - 50° = 40°
θ = 40°
By sine rule we have;
h/sin(50°) = d/(sin θ)
∴ h/sin(50°) = 60 ft./(sin 40°)
h = sin(50°) × 60 ft./(sin 40°) = 71.5052156 ft.
∴ The height of the tree, h ≈ 71.5 ft. by rounding to the nearest tenth

what is 11/4-3/8= what is it or get me the right answer
Answer:
2 3/8 is the answer
Step-by-step explanation:
11/4 - 3/8
We will find the LCM of 4 and 8, which is 8.
We will do 11/4*8, which 8/4 = 2 and 2*11 = 22
Then we will do 3/8*8 = 8/8 = 1 = 3*1 = 3
So the answer will be 22-3 = 19
8 = 8
Mixed Fraction = 2 3/8

I am one of the numbers represented on a number line when you divide the segment between -15 and 25 into 4 equal parts. I am positive and prime. What number am i?
Answer:
2, 3, 5, 7, 11, 17, 19, 23
Step-by-step explanation:
The segment between - 15 and 25 has 40 numbers given by
25 - -15
= 25 + 15
= 40
Divided into 4 segments, each would contain 10 numbers such that the
1st segment is from -15 to -5 (which is -15 + 10)
2nd segment is from -5 to 5 (which is -5 + 10)
3rd segment is from 5 to 15 (which is 5 + 10)
4th segment is from 15 to 25 (which is 15 + 10)
Given that the unknown number is prime and positive this may be
2 or 3 or 5 from the 2nd segment
7 or 11 from the third segment
17 or 19 or 23 from the 4th segment
What is the median?
A(18
B(27
C(33.2
D(34.5
Answer: 34.5
Step-by-step explanation:
First, write out all of the numbers from least to greatest.
which is (18,20,26,34,34,35,38,40,42,45)
Second, choose the number in the middle of the set of numbers you wrote out from least to greatest. (There are TWO numbers in this case, which are 34 and 35)
Lastly, since there are two numbers you add them both together and then divide by 2. (34+35=69 , 69 divided by 2 = 34.5)
Find the simple interest and amount when principal = Rs. 6000, rate = 6% per annum and time = 4 years
Given:
Principal = Rs. 6000
Rate of simple interest = 6% per annum.
Time = 4 years
To find:
The simple interest and amount.
Solution:
Formula for simple interest:
[tex]I=\dfrac{P\times r\times t}{100}[/tex]
Where, P is principal, r is the rate of interest and t is the number of years.
Putting P=6000, r=6 and t=4, we get
[tex]I=\dfrac{6000\times 6\times 4}{100}[/tex]
[tex]I=60\times 6\times 4[/tex]
[tex]I=1440[/tex]
Now,
[tex]Amount=Principal+Interest[/tex]
[tex]Amount=6000+1440[/tex]
[tex]Amount=7440[/tex]
Therefore, the simple interest is Rs. 7440 and the amount is Rs 7440.

Question 1 options:
112°
158°
136°
68°
Answer:
A. 112°Step-by-step explanation:
Angles QPS and QRS are supplementary as opposite angles of a cyclic quadrilateral.
Supplementary angles sum to 180°.
m∠QPS = 180° - m∠QRSm∠QPS = 180° - 68°m∠QPS = 112°Correct choice is A

You are planning a trip of 900 miles. Your car gets about 21 mpg. Gasoline costs $1.59 per gallon. How much should you budget for gas on this trip? Round answer to the nearest ten (10)
Answer:
$64.3
Step-by-step explanation:
Given the following
Total distance = 900miles
Rate per gallon = 21miles per gallon
rate = distance/time
Get the number of gallons used;
Number of gallons used = 900/21
Number of gallons = 42.857gallons
If coost of 1 gallon is $1.50
42.857gallons will cost 42.857 * 1.50
42.857gallons will cost $64.3
Hence he should budget $64.3 for the trip

Answer:

Step-by-step explanation:
Please help me solve this
Answer:
1st pic:
x = 60
y = 50
2nd pic:
y = 8
∠W = 28
∠Y = 128 degrees
∠X = 24
Step-by-step explanation:
first pic:
to find x, subtract 120 from 180 ⇒ 180 - 120 = 60
to find y, add 60 & 70 & subtract the sum from 180 ⇒ 180 - (60 + 70) = 50
2nd pic:
to find ∠Y, subtract 52 from 180:
180 - 52 = 128
to find y, use the following equation:
3y + 4y - 4 + 128 = 180
combine like terms:
7y + 124 = 180
subtract 124 from each side:
7y + 124 - 124 = 180 - 124
7y = 56
divide 7 on both sides:
[tex]\frac{7y}{7} = \frac{56}{7}[/tex]
y = 8
now we can find angles W and X
∠W = 4y - 4
we know that y = 8 so just substitute 8 for y
∠W = 4 x 8 - 4
∠W = 28
∠X = 3y
likewise, subtitute 8 for y
∠X = 3 x 8
∠W = 24
to check, add all angles and if they add up to 180, then its right:
24 + 28 + 128 = 180
180 = 180
Step-by-step explanation:
here's your solution
=> for first figure , (x + 120° ) = 180° [ linear pair]
=> x = 180° - 120°
=> x = 60°
=> now , we know sum of all angles of traingle = 180°
= >so, 60° + 70° + y = 180°
=> y= 180° - 130°
=> y = 50
now in figure second
=> 4y - 4 + 3y = 52° [ exterior angle equal to sum of two opposite interior
=> 7y - 4 = 52°
=> 7y = 52° + 4°
=> 7y = 56°
=> y = 56°/7
=> 8°
hope it helps
