Recall that the sum of the measures of the angles of a triangle is 180 degrees. In the triangle below, angle c has the same measure as angle b, and a measures 42 degrees less than angle b. Find the measure of each angle.

Step 1. Given c=b

Step 2. a=b-42 since angle a measures 42 less than angle b.

Step 3. Then, b-42+b+b=180 since c=b and the three angles add to 180 degrees.

and and

Step 4. Check if the angles equal to 180...74+74+32=180 which it does.

Step 6. ANSWER: Angle a is 32 degrees and angles b and c is each 74 degrees.

I hope the above steps and explanation were helpful.
