Answer:
160°
Step-by-step explanation:
Minor Arc NR is equal to the measure of its central angle, S.
S and 20 are supplementary angles, so they add up to 180.
So, s +20 =180
S = 160, so NR = 160 as well
Answer:
D. 8*x
Step-by-step explanation:
Hello there! A regular octagon has eight sides with the same extension. The perimeter is the addition of each of them. If each side is x units length, then x + x + x + x + x + x + x + x = 8*x is its perimeter.
Answer:
The answer is that x = 5.69 and y = 12.79
Step-by-step explanation:
To find x, we need use the Sin function. Sin of any angle is equal to the ratio of opposite to hypotenuse. This allows us to solve using the following equation.
Sin(ANGLE) = OPP/HYP
Sin(24) = OPP/14
14Sin(24) = OPP
5.69 = OPP
5.69 = x
We can do the same using the Cos for the adjacent side.
Cos(ANGLE) = ADJ/HYP
Cos(24) = ADJ/14
14Cos(24) = ADJ
12.79 = ADJ
12.79 = y
Answer:
26
Step-by-step explanation:
7.5% of 20$ is 1.50, so you add 19.99+1.50 and you get 21.49$. Then all you do is subtract 550 from 21.49 until you can't. You can subtract 21.49 from 550 26 times.
Answer:
115 degrees
Step-by-step explanation:
14x+3+4x+10=157
14x+4x+3+10=157
18x+13=157
18x=157-13
18x=144
X=8
14x+3
(14×8)+3
112+3=115
