The angle measures of triangle ABC are as follows: The measure of angle A is 30
The measure of angle B is 2x+10
The measure of angle C is 5x

What is the value of x?

20°

Step-by-step explanation:

< A + <B + <C = 180° { being sum of angles of triangle }

30° + 2x + 10° + 5x = 180°

40° + 7x = 180°

7x = 180° - 40°

7x = 140°

x = 140° / 7

x = 20°
