Question

find the value of x of exterior angle and interior angle​

Answer 1

Step-by-step explanation:

25+(x+15)=3x−10

⟹25+x+15=3x−10

⟹40+x=3x−10

⟹40+10=3x−x

⟹50=2x

⟹

2

50

=x

⟹25=x

.°. x = 25°

Then,

The measure Exterior angle of the triangle

= 3x-10

= 3 × 25° - 10

= 75° - 10

= 65°

Answer 2

Answer:= 65°
