Answer:
x = 25
Step-by-step explanation:
We know that A and M are on a line, which is 180 degrees, and the little square means 90 degrees. So, ∠RAM = 180 - 90 = 90 degrees.
∠RAM = ∠RAX + ∠XAM
90 = (2x - 10) + (-3x + 125)
Now, simply combine like terms and solve for x:
90 = 2x - 3x - 10 + 125
90 = -x + 115
x = 115 - 90 = 25
Thus, x = 25.

Answer:
Identity is verified.
Step-by-step explanation:
We have to verify the identity 
To prove any identity we always prove one side(either left hand side or right hand side) of the equation equal to the other side.
In this identity we take the left hand side first

(as we know cos(a+b) = cosa×cosb-sina×sinb)


= - sinx ( Right hand side)
Hence identity is proved.
