Missing angles are: 33, 85, 65, 53, 86, 62, 32, 33, 62, 85, 65, 53, 84, 32, 64, 95, 85, 95 degrees.
To find the missing angles, use the fact that the sum of the three interior angles in a triangle = 180°. In this diagram, there is one large triangle being split into many smaller triangles with straight lines. While they seem close to the halfway points, there are no 90° in sight. So we must use the knowledge that a straight line has a degree of 180°.
That’s what I do in the photo below (sorry it was easier to draw it):
I hope this helps!
