Question

one side of a triangle is produced and the exterior angle so formed is 120 degree if the interior opposite angles be in the ratio 3:5 find the measure of the each angle of the triangle​

Answer 1

Given ratio is 3 : 5

3x + 5x = 120

8x = 120

x = 15

3x = 3(15) = 45°

5x = 5(15) 75°

The two angles are 45° and 75°

hope it helps !!

Answer 2

answer

the two angles are 45° and 75°

Step-by-step explanation:

Give ratio is 3:5

3x + 5x = 120

8x = 120

x = 15

3x = 3 (15) = 45°

5x = 5 (15) 75°

the two angles are 45° and 75°
