The answer im just guessing but teachers like to do false false true true so sorry if im wrong
Answer:
56°
Step-by-step explanation:
The two marked angles are supplementary, so total 180°.
(2x +8) +(x -2) = 180
3x +6 = 180 . . . . . . . . . . collect terms
x + 2 = 60 . . . . . . . . . . . divide by 3
x = 58 . . . . . . . . . . . . . . subtract 2
∠DCB = x-2 = 58 -2
∠DCB = 56
Looking at the expression, we see that the only common factor shared between these three terms is x.
We factor out x:
x(2x2 + 4x - 1)
We can no longer find any common factors, so this is the final answer.
Answer:
22.5
Step-by-step explanation:
Inscribed Angle =1/2 Intercepted Arc
F = 1/2 (45)
<F = 22.5
