Question

7. Angles of a triangle are x, (x + 10) and (x + 20). Find the measure of the hig
find the value of angle​

Answer 1

Answer:

50 degree , 60 degree and 70 degree

Step-by-step explanation:

1st angle is x

2nd angle is x+10

3rd angle is x+20

sum of interior angle of a triangle is 180 degree

x + (x+10) + (x+20) = 180 degree

3x + 30 = 180 degree

3x = 180 - 30

3x = 150

x = 150/3

x = 50 degree

Anngles of triangle are 50 degree , 60 degree , 70 degree
