In triangle abc, the measure of angle b is 60 more than a. the measure of angle c is eight times the measure of a. if x represents the measure of angle a, set up and solve an equation to find the measure of angle a.

the measure of angle A is 12 degrees

Step-by-step explanation:

Let x represent the measure of angle A.

Let y represent the measure of angle B.

Let z represent the measure of angle C.

In triangle ABC, the measure of angle B is 60 more than A. This means that

y = x + 60

The measure of angle C is eight times the measure of A. This means that

z = 8x

Also, the sum of the angles in a triangle is 180 degrees. Therefore

x + y + z = 180 - - - - - - - - - 1

Substituting y = x + 60 and z = 8x into equation 1, it becomes

x + x + 60 + 8x = 180

10x + 60 = 180

10x = 180 - 60 = 120

x = 120/10 = 12

Step-by-step explanation:

measure of A=x

∠C=8x

∠B=x+60

in a triangle sum of angles=180°

x+8x+x+60=180

10x=120

x=12

m∠A=12°
