B, if you want this answer described let me know <span />
3x-25=2x-10 add 25 on both sides
3x=2x+15 then subtract 2x on both sides
<span>X=15 </span>
Plug in x to "3x-25" which would equal 20
<span>M< L = 20 so, 180-20= 160 </span>
<span>M=160

Tangent secant theorem which in this case says
6² = x (x + x) = 2x²
36 = 2x²
18 = x²
x = 3√2
Answer: x = 3√2
