Question

Call the three angles of a triangle ∠1,∠2,∠3

The measure of ∠2 is twenty degrees greater than that of ∠1; the measure of ∠3 is thirty degrees less than twice that of ∠1If x is the measure of ∠1, then which of the following equations would we need to solve in order to calculate the measures of the angles?

Answer 1

Angle Angle Similarly Theory

Explanation:

calculate one then another leaving you with the final angle. and a triangle is 180 degrees
