Question

I need help in number 2 ASAP please

Answer 1

angle A + angle B + angle C = 180° [Sum of all angles of a triangle is 180°]

=> 2x+1 + x+15 + x = 180°

=> 4x + 16 = 180°

=> 4x = 180° - 16°

=> 4x = 164°

=> x = ($\frac{164}{4}$)°

=> x = 41°

angle A = 2x+1 = 2×41 +1 = 82 + 1

=> 83°

angle B = x+15 = 41+15

=> 56°

angle C = x

=> 41°

HOPE IT HELPS
