An Isosceles triangle has two even parts, you add them up. For example 60 degree plus another 60 degree angle is 120 degrees. And the limit is 180 degrees, so in order to get that last angle, you'd have to subtract 160 from 180. And that'd be 20 degrees. I couldn't see the question but I hope this helps you in a way
It has nothing to do with the Moon. It is the time of year when, over the northern hemisphere, the Sun is near or at its highest apparent position in the sky and the rays are most direct Earth's axial tilt points the Northern Hemisphere more towards the sun in June, causing the sun to ride higher in the sky. Summer for us, Winter South of the Equator.
