Answer 1

Answer:

50, 70, 60

Step-by-step explanation:

We know exterior angle = sum of opposite two interior angle

Given ratio of exterior angle is 5:7

Let common factor be X

So, ratio = 5x:7x

ATP,

5x+7x = 120

=> 12x = 120

=> x = 120/12

=10

So, angles are 5 × 10 = 50

7 × 10 = 70

We know sum of all angles of a triangle is 180 degree

So, first two interior angles are 50 and 70 degrees

Let the third angle be ydegree

So, y+50+70 = 180

=> y = 180 - 120

= 60

Angles of the triangle are 50, 70 and 60 degrees
