Question

Determine the missing angle measures in each triangle

Answer 1

50°

Explanation:

We can calculate the value of the missing angle, since there is a right angle (that is, 90°) and the other is 40 °, we apply the property that says that the sum of all the internal angles of a triangle is equal to 180°, Thus:

`180=90+40+x`

Solving for x:

`\begin{gathered} x=180-90-40 \\ x=50\text{\degree} \end{gathered}`
