Question

Measure of 3 angles of a triangle Are x,4x+10, 4x-10

​

Answer 1

1st angle is 20

2nd angle is 90

3rd angle is 70

X+4x + 10+4x -10=180

9x=180

X= 20

Answer 2

Step-by-step explanation:

x (4x+10)( 4x-10)= 180°

9x+10-10=180°

9x=180°

x=180/9

x=20

4x+10

4×20+10

80+10

=90°

4x-10

4×20-10

80-10

=70°
