A ladder is leaned against a wall that is six feet tall, so that the top of the ladder is resting on the top
of the wall. The ladder is inclined at an angle of thirty degrees. Find the distance from the bottom of
the ladder to the base of the wall. Round your answer to the nearest tenth of a foot. Do not include
units in your answer.
Answers
Answer:
[tex]10.4[/tex]
Step-by-step explanation:
The ladder leaning against the wall forms a right triangle with the wall and the ground. Therefore, we can use basic trig for a right triangle to solve this problem.
In a right triangle, [tex]\tan\theta=\frac{\text{opp}}{\text{adj}}[/tex]. Therefore, we have the following equation, where [tex]x[/tex] is distance between the bottom of the ladder to the base of the wall:
[tex]\tan 30^{\circ}=\frac{6}{x},\\x=\frac{6}{\tan 30^{\circ}},\\x\approx \boxed{10.4}[/tex].

Find the 11th term of the geometric sequence 6, -18,54, ...
Answers
an = a1 * r^n-1 (formula)
a11 = 6 * (-3)^11-1
a11 = 6 * 590949 = 354294
a11 = 354294
Answer:
354294
Step-by-step explanation:
a1 = 6, r = -3
an = a1 * r^n-1 (formula)
a11 = 6 * (-3)^11-1
a11 = 6 * 590949 = 354294
a11 = 354294
If Triangle ABC~ triangle DEC, find the value of x and the scale factor from DEC to ABC
Answers
Answer:
see explanation
Step-by-step explanation:
The scale factor is the ratio of corresponding sides, image to original, that is
scale factor = [tex]\frac{AC}{DC}[/tex] = [tex]\frac{25}{20}[/tex] = [tex]\frac{5}{4}[/tex]
Then
[tex]\frac{AB}{DE}[/tex] = [tex]\frac{3x-2}{2x}[/tex] = [tex]\frac{5}{4}[/tex] ( cross- multiply )
4(3x - 2) = 10x
12x - 8 = 10x ( subtract 10x from both sides )
2x - 8 = 0 ( add 8 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4

Answer:
c = √73
Step-by-step explanation:
The Pythagorean theorem tells you that ...
c² = a² + b²
The sides you choose to call 'a' and 'b' don't matter. We can let 'a' be the left side and 'b' be the top side. Then we have ...
c² = 3² +8² = 9 + 64 = 73
Taking the square root gives ...
c = √73
Answer:
c = [tex]\sqrt{73}[/tex]
Step-by-step explanation:
c is the hypotenuse ( side opposite to the right angle )
So,
[tex]c^{2}[/tex] = [tex]8^{2}[/tex] + [tex]3^{2}[/tex] (Pythagoras theorem)
c = [tex]\sqrt{64 + 9}[/tex]
c = [tex]\sqrt{73}[/tex]
Find the measure of angle a.
Answers
Answer:
a = 127°
Step-by-step explanation:
The 3 angles lie on a straight line and have a sum of 180°, that is
15° + a + 38° = 180°
53° + a = 180° ( subtract 53° from both sides )
a = 127°

You need to get rid of the fraction first and to do that you muliply the whole equation by 5 so that your new equation reads 4x+25=45. Then you subtract 25 from both sides so you have 4x=20. Divide both sides by 4 so x=5.

Question 3 (1 point) A right triangle has a leg length of 21 and a hypotenuse of 75. Find the missing leg.
Answers
Answer:
72
Step-by-step explanation:
Given that :
Triangle is right angled ;
Leg length = 21 ; hypotenus = 75 ; Length of missing leg =?
From Pythagoras :
Length of leg 2 = sqrt[(hypotenus )² - (length of leg1)²]
Let length of leg 2 = x
x = sqrt[(75 ² - 21²)]
x = sqrt(5625 - 441)
x = sqrt(5184)
x = 72
A right triangle has a leg length of 21 and a hypotenuse of 75. Find the missing leg.
