Answer:
46
Step-by-step explanation:
Angle CED and GHE are equal as the lines are parallels. Also, the line rom D to F will be a total of 180.
Therefor, substract the angle FEC from 180 and you get the angle CED which is equal to GHE
Answer:
Step-by-step explanation:
average of x-coordinates = (7+1)/2 = 4
average of y-coordinates = (-3-1)/2 = -2
center of circle: (4,-2)
radius = distance between (1,-1) and (4,-2)
= √((4-1)²+(-2-(-1))²)
= √10
equation of circle:
(x-4)² + (y+2)² = 10
Answer:
21³
it's the answer coz in division power is subtracted
mark me brainliest
First off, sin 2 theta = 2 sin theta cos theta. Also, the answer to your question is no. There are multiple double angle formulas, and it is important that you remember them so that you can answer questions correctly.
