FOR BRAINLIST!!

The sum of the measures of three angles is 90 The measure of angle M is 2x The measure of angle N is 3x 8 The measure of angle Q is 7x 2 What is the value of x class=

Respuesta :

Answer:

A

Step-by-step explanation:

Equation

2x + 3x + 8 + 7x - 2 = 90        

Solution

Combine like terms on the left

12x + 6 = 90                    Subtract 6 on both sides

12x = 90 - 6

12x = 84                         Divide by 12

x = 84/12

x = 7
