I'm guessing the total amount of degrees is 360 degrees.
67 + 130 + 72 = 269
360 - 269 = 91
Answer = 91°
Hope this helped☺☺
Check the picture below.
keeping in mind that the point of tangency for a radius line and a tangent is alway a right-angle, since the "red" chord is parallel to the "green" tangent line outside, then the chord is cutting the "green" radius there in two equal halves at a right-angle, as you see in the picture.
we know the chord is 10 units long, so 5 + 5, since is perpendicularity with the radius will also cut the chord in two equal halves.
anyhow, all that said, we end up with triangle you see on the right-hand-side, and then we can just use the pythagorean theorem.

Answer:
-3.25 Didn't see the whole paper so correct me if I'm wrong.
Step-by-step explanation:
−2.5+0.25+−1.25+−1.5
+1.25+0.5=-3.25
Answer:
UV=142
Step-by-step explanation:
21x-13=10x+31
+13 +13
21x=10x+44
-10x=-10x
11x=44
÷11 ÷11
x=4
now substitute 4 in place of x (only have to solve one)
21(4)-13= 71
now multiply your answer by 2
71×2=142
