Answer:
We know that the figure has a symmetry
angle 1 = angle 2
angle 1 =180°-(18°+90°) = 180° - 108°=72°
Therefore, <em><u>angle 2 =72°</u></em><em><u>.</u></em>
Because all 3 sides are given for both triangles you can use the SSS theorem
It's 77.472 , but since you probably need too round it will be 77.5
