Question

please tell me answer

Answer 1

$(2x - 5) + (x - 10) = 90 \\ 2x - 5 + x - 10 = 90 \\ 3x - 15 = 90 \\ 3x = 90 + 15 \\ 3x = 105 \\ x = \frac{105}{3} \\ x = 35 \\ \\ pls \: mark \: me \:a s \: brainleist$
BOC= 35-10
BOC= 25°

Answer 2

Hope it helps u

angle BOC + angle COA = angle AOB

.°.(x-10)°+(2x-5)° =90°

.°. x-10°+2x-5° =90°

.°. x+2x-10°-5° =90°

3x-15°=90°

3x=90°+15°

3x=105°

.°.x=105/3

x= 35°

.°. angle BOC = (x-10°)

= 35°-10°

= 25°
