How do i solve a missing angel with an answer in radical form? I will provide the full photo.

Answer 1

According to the triangle given we know the measure of 2 of the 3 angles of the triangle, it has a right angle of 90° and and a 60° angle.

According to the theorem every triangle must fulfill that the addition of its inner angles must be equal to 180°

Call the missing angle z and make an equation

`\begin{gathered} z+90+60=180 \\ z=180-60-90 \\ z=30 \end{gathered}`

the missing angle must be equal to 30°.
