Question

Solving linear functions The sum of the measures of the triangles of all triangles is 180 degrees if one angle of the triangle measures 45 degrees, and the other two angles are equal, what is the measure of each of the other two angels.

Answer 1

Solution

Step 1:

Let the other two equal angles be x.

Step 2:

Sum of angles in a triangle is 180 degrees:

$\begin{gathered} x\text{ + x + 45 = 180} \\ \\ 2x\text{ = 180 - 45} \\ \\ 2x\text{ = 135} \\ \\ x\text{ = }\frac{135}{2}\text{ = 67.5} \end{gathered}$

Answer

The measure of the other two angles is 67.5
