Calculate the size of θ in the given diagram ( see image).
O is the center of the circle.​

∅ = 42°

Step-by-step explanation:

90 - 48 = 42° because 48 and 42 are complimentary angles (add up to 90°)

because the radii lines form an isosceles triangle, ∠∅ also = 42°

90-48=42 grades because 48 and 42 are complimentary angles (add up to 90 grades).

i am sure it will be 90 degrees.

step-by-step explanation:

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
