Atriangle contains the angles 75" and 45". what is the missing angle in the triangle

Finding the 3rd Angle in a Triangle. If you add all three interior angle measures together in a triangle it will always equal 180°.

Im sorry but what on

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
