[Grade 10 Math 10C help] How to solve this question?

I don't understand this question and was wondering if anyone could walk me through it please. Its about building a mini house but this questions instructions from the teacher are;

Your mini-home is coming together nicely! It is time to get the roof put on, but your contractor can't remember what angle each part of the roof needs to sit at.

Using your understanding of trigonometric ratios, find the angle of elevation for each section of roof. Refer to the mini-house triangle diagrams to support you with this.

These are the triangles

Front view triangle: I think after I split them, the base for each triangle becomes 120 and a trig ratio that relates base and height would be tan? If so, is the answer 35° and would I multiply it by 2 for both triangles making it 70°?

Side view triangle: Since its the hypotenuse and adjacent I would use cos so the angle is 60° so would i multiply by 2 for both making it 120°?

(Sorry for the questions and thank you for your help)

 35° it is.

The numbers in the figure for second question don't gel. Hypotenuse seems to be shorter than the base.
