The value of 
<u>Solution:</u>
Given: 
To find: The value of (h*h)(10)
We know that, 
which is,

On solving we get,

So, for x = 10 it will be,

Hence, the required value is 10.
I believe the answer is D) 35°.
We have a 90° angle, and a 55° angle.
(It's 55° because this other angle is supplementary to the angle that equals 125°).
So, 90 + 55 + 35 = 180 Which is the answer we want!
The 2 angles given are vertical angles, which mean they are the same.
So we have: 3x +1 = 64
Subtract 1 from each side:
3x = 63
Divide both sides by 3:
X = 63 / 3
X = 21
The answer is A.
The correct answer for solving for x is: x ≤ 9
