Answer 2

d would be 90 since the triangle is a right triangle

Answer 3

for a I want say 30 and for b I want to say 60,

Answer 4

but to get the actual answer would have to use the archs 76 and 32 degrees

Answer 5

Explain : )

Answer 6

since the angles are inscribed into the circle we don't have to solve for radians

Answer 7

and inscribed angles are always half of the minor arc

Answer 8

Mind showing me the theorem for this or something haha?

Answer 9

a triangle adds to 180 degree and a circle adds to 360 degree, half the arcs and input the angle degrees. Once we have all degrees we'll see if everything adds up for proof

Answer 10

c should be the easiest to find out

Answer 11

180 -76 = c 180/2 = d d is also a right angle; c/2 = b & 76/2 =a; a+b+d =180

Answer 12

@kikuo bit confused by the diagram. Why are some angles outside of the circle?
I can tell you angle D is a right angle since all angles in semi circles are right angles.

Answer 13

I'm not sure myself.
