Question

Find the measure of the third angle of a triangle if the measures of the other two angles are given.109.7 and 47.1A. 23.2B. 33.2C. 36.7D. 43.2

Answer 1

To find the measure of the third angle we must use the next statement:

We have two angles so we can represent the situation with a equation

`109.7+47.1+x=180`

Where x is the third angle.

Now, we must solve the equation for x

`\begin{gathered} x=180-109.7-47.1 \\ x=23.2 \end{gathered}`

Finally, the measure of the third angle is 23.2
