Answer 1

In a right triangle one of the angles is 90º.

In all the triangles the sum of the internal angles is always 180º.

Then, as you have a right triangle with an anlge of 10º and one angle of 90º :

`10º+90º+x=180º`

x is the value of the third angle:

`\begin{gathered} x=180º-90º-10º \\ \\ x=80º \end{gathered}`Then, the third angle is 80º
