Answer: 22.5 degrees
Step-by-Step Explanation:
As we can see, we are given a line, which is a straight angle. Hence, it will be of 180 degrees.
=> All the angles sum up to 180.
Therefore,
=> 3x + x + 90 = 180
= 4x + 90 = 180
= 4x = 180 - 90 = 90
=> x = 90/4 = 22.5
Therefore, x = 22.5 degrees
Verification:
=> 3x + x + 90 = 180
= 3(22.5) + 22.5 + 90 = 180
= 67.5 + 22.5 + 90 = 180
= 90 + 90 = 180
=> 180 = 180
=> LHS = RHS
The equation for the area of a triangle is (base × height)/2.
In this triangle your base is 12 and your height is 8.
Therefore you do (12 × 8)/2 = 96/2 = 48

Answer:
149
Step-by-step explanation:
Answer:
c.29 is the answer to your question
using pythagorean theorem we can get h
![17^2=15^2+h](https://tex.z-dn.net/?f=17%5E2%3D15%5E2%2Bh)
![h=\sqrt[]{64}\text{ =8}](https://tex.z-dn.net/?f=h%3D%5Csqrt%5B%5D%7B64%7D%5Ctext%7B%20%3D8%7D)
so we get h as 8.
A=bxh
h=8 b= 28
so,A=224in
