Step-by-step explanation:
In triangle BAC, by Pythagoras theorem:
[tex]AC^2 = BC^2 -BA^2 [/tex]
[tex]AC^2 = (15)^2 -(9)^2 [/tex]
[tex]AC^2 = 225 - 81[/tex]
[tex]AC^2 = 144[/tex]
[tex]AC = \sqrt {144} [/tex]
[tex]AC = 12\: cm [/tex]
In triangle ABD,
[tex] \tan \angle ABD =\frac{AD}{AB} [/tex]
[tex] \tan \angle ABD =\frac{5}{9} [/tex]
[tex] \angle ABD =\tan^{-1}\frac{5}{9} [/tex]
[tex] \angle ABD =29.054604099\degree [/tex]
[tex] \angle ABD =29.05\degree [/tex]
Next, in triangle ABC, by sine rule:
[tex] \frac{\sin \angle ABC}{AC}=\frac{\sin \angle BAC}{BC}[/tex]
[tex] \frac{\sin (\angle ABD+\angle DBC) }{12}=\frac{\sin 90\degree}{15}[/tex]
[tex] \frac{\sin (29.05\degree+x) }{12}=\frac{1}{15}[/tex]
[tex] \sin (29.05\degree+x) =\frac{12}{15}[/tex]
[tex]29.05\degree+x = \sin^{-1}\frac{12}{15}[/tex]
[tex]29.05\degree+x =53.130102354\degree [/tex]
[tex]29.05\degree+x =53.13\degree [/tex]
[tex]x =53.13\degree- 29.05\degree[/tex]
[tex]x =24.08\degree [/tex]
[tex]x \approx 24\degree [/tex]

Which of the following statements is true?
What does r stand for in the formula 2.rr.?
Answer:
r = radius of circle
Step-by-step explanation:
The circumference of a circle is given by :
C = 2πr
Where
r is the radius of the circle
In this problem, we need to say that what does r represents in the given formula. It means we can say that r stands for the radius of the circle.

The ratio of Ali's to Beth's score is 5:3. Ali
scored 10 more marks than Beth. Clare scored
7 more than Ali. Find the score of all three.
Answer:
Ali 25
Beth 15
Clare 32
Step-by-step explanation:
Here, we want to get the score of the three
let Ali’s score be x
He scored 10
more than Beth; Beth score will be x-10
Let us now work with the ratio
x/x-10 = 5/3
3x = 5(x-10)
3x = 5x - 50
5x-3x = 50
2x = 50
x =
50/2
x = 25
Beth will
score 25-10 = 15
score had 7 more than Ali,
25 + 7 = 32

To get the area of a right triangle (a triangle with an angle of 90 [represented by the box in the corner]) you have the formula of
Area = (a*b) divided by 2
a = one side of the triangle
b = another side of the triangle
Neither side are the hypotenuse.

the question is "get y by itself" and the equation is 5x + 5y =15
Answer:
y=3-x
Step-by-step explanation:
Answer:
First we get y on one side by itself.
5x+5y=15
We move x over to the other side.
5x-5x+5y=15-5x
Simplify.
5y=15-5x
Now we remove the coefficient from y.
5y/5=(15-5x)/5
Simplify.
y=15/5-5x/5
y=3-x
The answer is y=3-x

Which statement best describes the relationship between the lengths of the sides of the triangle shown below?
A. r squared is equal to t squared minus s squared.
B. The square root of t is equal to r plus s.
C. s squared equals t squared plus r.
D. s plus t is equal to r squared.
Answer:
the answer is c
Step-by-step explanation:
The relationship between the lengths of the sides of the triangle is as follows: r² = t² - s².
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
The right triangle is given in the question, as shown
As per the given figure, the right triangle has
The hypotenuse = t
Let, perpendicular = r and base = s
According to Pythagoras's theorem,
In a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
So, perpendicular²+base²=hypotenuse²
⇒ r² + s² = t²
This can be rewritten as
⇒ r² = t² - s²
Hence, the correct answer would be an option (A).

The sum of two numbers is 63 and the difference is 5. What are the numbers?
Answer:
Numbers are 29 and 34
Step-by-step explanation:
Let x = one number
let y = second number
x + y = 63
x - y = 5
substitution method, x = 5 + y
5 + y + y = 63
2y + 5 = 63
2y = 58
y = 29
Find value of x: x - 29 = 5
x = 34

A water gauge in a pond measured 2358 in. At the beginning of the week. After five days of rain, the gauge read 3414 in. By how much did the water level rise?
Answer:
1056 inches
Step-by-step explanation:
Given that :
Initial measurement = 2358 in
Guage level after 5 days of rain (final reading) = 3414 in
Change in water level rise :
Final reading - Initial reading
(3414 - 2358) in
= 1056 inches
