SOLUTION: Okay it says The variable expressions represent the angle measures of a triangle. Find the measure of each angle. Then classify the triangle by it's angles. 1. m angle A= (x+30)

Question 365350: Okay it says The variable expressions represent the angle measures of a triangle. Find the measure of each angle. Then classify the triangle by it's angles.
1. m angle A= (x+30) degrees
m angle B= x degrees
m angle C= (x+60) degrees
What does this mean?

The sum of the three angles must be equal to 180 degrees. So

Start with the given equation.

Combine like terms on the left side.

Subtract from both sides.

Combine like terms on the right side.

Divide both sides by to isolate .

Reduce.

Answer:

So the solution is

So the three angles are:

Angle A: degrees

Angle B: degrees

Angle C: degrees

Since one angle is a 90 degree angle, this means that we have a right triangle.
