Question

please answer.....it is necessary
​

Answer 1

Hey Mate!!!!

Here's your answer,

AO is perpendicular to OB.(That means 90° right angle.)

Therefore,

2x-5+x-10=90

3x-15=90

3x=90-15

3x=75

x=25°

I have spent my own time to answer your question clearly.

As appreciating my efforts mark my answer as the brainiest plz.

Answer 2

Since AO perpendicular to BO,

<AOC+<BOC = 90°

2x-5 + x-10 = 90

3x = 90+15 = 105

x = 35

Therefore,

<AOC = 2×35 -5 = 70-5 = 65

<BOC = 35-10 = 25

Hope this is helpful to you
