Question

angle 1 and angle 2 are vertical angles. if the measure of angle 1 is (6x+11)° and measure of angle 2 is (10x-9)° find measure of angle 1.​

Answer 1

Angle 1 = 41°

Explanation:

Since they are both vertical angles

(6x+11)° = (10x-9)°

6x - 10x = -9 - 11

-4x = -20

4x = 20

x= 5.

Therefore,

Angle 1 = 6(5) + 11

Angle 1 = 30 + 11

Angle 1 = 41°
