1. Write a list of steps that are needed to find the measure of ∠B.
∠B is an equilateral triangle with its left bottom corner being 72 degrees and it has a straight line going out straight and the corner created from that line next to the right bottom corner is 113 degrees
Here are the steps to find the measure of ∠B:
1. Draw the triangle ∠B with its left bottom corner given as 72 degrees and its adjacent corner given as 113 degrees.
2. Identify that the third corner of ∠B will also have a measure of 72 degrees since it is an equilateral triangle, which means all angles are equal.
3. Add all three angles' measures to solve for the total degrees in ∠B.
4. The total degrees of ∠B should be the sum of three angles, which would be 72 degrees + 72 degrees + 113 degrees = 257 degrees.
Therefore, the measure of the ∠B is 257 degrees.
I said, "The triangle is equilateral, seeing as the sides don't seem to have different sizes, meaning all the corners are 72 degrees, so to find ∠B, we add. So 72 degrees + 72 degrees + 113 degrees = 257 degrees
∠B = 257 degrees." Does that sound correct?
