Answer:
m<1: 51
m<2: 61
m<3: 29
Step-by-step explanation:
m<1 = 51, because to find the 3rd angle, you need to add the other two angles and then subtract 180 from that answer.
61 + 68 = 129
180 - 129 = 51
m<2 = 61, because it's a vertical angle, meaning that the angle that's opposite to it exactly, is the same. So since the angle opposite to m<2 is 61, that's what the answer would be.
m<3 = 29, because all you need to do is add 90 and 61, and then subtract 180 by the answer. I got 90 as one of the angle measurements because there's a right triangle, meaning it's 90. Then since we already know what angle 2 is (61) then all you need to do is add:
90 + 61 = 151
Then subtract:
180 - 151 = 29
Answer:
8
Step-by-step explanation:
The measure of an inscribed angle is half the measure of the intercepted arc.
m<T = (1/2)m(arc)SU
9x - 25 = 47
9x = 72
x = 8
Answer: x = 8
