Question

find the measure of each angle​

Answer 1

Answer:

By angle some property

sum of all angles of triangle is 180°

given <A = x+10°

<B = 3x+5°

<C = 2x+15°

<A+<B+<C = 180°

x+10°+3x+5°+2x+15° = 180°

6x+30° = 180°

6x = 180°-30°

6x = 150°

x = 150°/6

x = 25°

Therefore <A = x+10° = 25°+10° = 35°

<B = 3x+5° = 3×25° + 5° = 80°

<C = 2x+15° = 2×25°+15° = 65°
