Question

2. A triangle has 3 angles. The measure ofangle 1 is 89 degrees. The measure ofangle 2 is 36 degrees. What is the measureof the third angle?Show your work for finding the mission angle measure. What is the missing angle?

Answer 1

Step 1:

Let the measure of the third angle be x.

Step 2

Th sum of angles in a triangle is 180 degrees.

`\begin{gathered} x\text{ + 89 + 36 = 180} \\ \\ x\text{ + 125 = 180} \\ \\ x\text{ = 180 - 125} \\ \\ x\text{ = 55} \end{gathered}`

Final answer

The missing angle is 55
