Question

give me answer of Q.5 please​

Answer 1

Step-by-step explanation:

AOB is a right angle

hence 2x-5-x-10=90°

x-15=90

x= 105 substitute the other values

Answer 2

Answer:

AOC=65°, BOC=25°

Step-by-step explanation:

(2x-5°)+(x-10°)=90°

2x-5+x-10=90

3x-15=90

3x=90+15

3x=105

x=105/3

x=35

2x-5°=2(35)-5

2x-5°=70-5

2x-5°=65°

x-10°=35-5

x-10°=25°
