C
Step-by-step explanation:
Answer:2x times 2
Step-by-step explanation:
I am assuming from What I have found is that a is the base , b is angle between a and x and x is the hypotenuse .
So we know that
cos θ =base/hypotenuse
here θ = 3π/8 =67.5 degree
cos 67.5 =0.38268
so
0.38268=a/x
x=25/0.38268
x=65.32873
GX is the angle bisector. Answer is C
25x^2 - 16 =
(5x + 4)(5x - 4) <==
