Question

pleaseeeeeeee helpppp!!! Find the missing angel measurements of angle 1,4,7,10,13 please consider how many degrees are in a triangle while solving this please please help, this is for geometry

Answer 1

Answer: ∠1 = 52°, ∠4 = 40°, ∠7 = 100°, ∠10 = 49°, ∠13 = 65°

Explanation:

There are three formulas you need to find the angles. Each formula is based on where the vertex lies.

On the circle: Measure of the angle = (1/2) the arc

∠4 = (1/2)°80 ∠10 = (1/2)(18° + 80°) ∠13 = (1/2)130°

= 40° = (1/2)98° = 65°

= 49°

Inside the circle: (1/2) Sum of the Big arc and Little Arc

∠7 = (1/2) (130° + 70°)

= (1/2)200°

= 100°

Outside the circle: (1/2) Difference of the Big arc and Little Arc

∠1 = (1/2)[(62° + 130°) - (70° + 18°)]

= (1/2) (192° - 88°)

= (1/2)104°

= 52°

Below is the solution for ALL of the angles
