Question

in a triangle an exterior angle is 7x and its opposite interior angles are 3 X + 16 and 3 X + 4 find the biggest angle​

Answer 1

Answer:

∠A

Step-by-step explanation:

(3x+16) + (3x+4) = 7x        ...ext. angle property

6x+20= 7x

20 = x

Therefore, the angles are

∠A = 3(20)+16 = 76°

∠B = 3(20)+4 = 64°

∠C = 180-(A+B)                  ...Angles summ property

∠C = 180-140 = 40°

Therefore, the biggest angle is ∠A

Answer 2

Step-by-step explanation:

Angle A is the biggest angle of all.
