Answer:
<h2>66 and 66</h2>
Step-by-step explanation:
opposite angles are equal
12x - 18 = 8x + 10
combine similar terms:
12x - 8x = 10 + 18
4x = 28
x = 28/4
x = 7
plugin the value of x=7 back into the equation to solve the angle
= 12x - 18
= 12(7) - 18
= 66
= 8x + 10
= 8(7) + 10
= 66
Well, if you cut a circle in 4 parts, each part will equal 90 degrees. But if you cut one of those parts in half again it will cut the degrees in half. Thus, making the degrees of that half a part 45. Your answer should be 45 degrees.
to find the answer u have to multiply all the sides
