Answer 1

Answer:

9x +7x+2x=180

18x=180

x=180/18=10

So, the angles are 90,70,20 degree

Answer 2

Answer:

ans1. 50

ans2. 90, 30

Explanation:

the sum of all the angles of a triangle is 180. subtracting 60 and 70 will give us 50.

in a right angle triangle there is an angle of measure 90 so subtracting 90 and 60 will give us 30
