Answer:
x = 5.5
EF = 14
Step-by-step explanation:
We can use ratios to solve
AG 7
----------- = -----------------
EG 2x+3
We know that EG is 2 times AG since A is the midpoint
AG 7
----------- = -----------------
2 AG 2x+3
Canceling like terms
1 7
----------- = -----------------
2 2x+3
Using cross products
1 (2x+3) = 2*7
2x+3 = 14
Subtract 3 from each side
2x+3-3 = 14-3
2x =11
Divide by 2
x = 11/2
x = 5.5
EF = 2x+3 = 2*5.5+3 = 14
Answer:
AGREE!
Step-by-step explanation:
"I agree with Lin, she used the correct formula to get this answer"
The fraction with the smaller denominator is the greater number.
Answer:
You use cotx = cosx/sinx.
Step-by-step explanation:
I guess you mean cotx sinx = cosx.
You substitute the identity cotx = cosx / sinx:
cotx sinx = (cosx / sin x) * sin x
The sin x ' s cancel to give cosx.
The answer is C
explanation:
In all triangles the interior angles add up to 180 degrees. the top angle of this triangle is 90 degrees and 180-90=90, so the bottom 2 angles add up to 90. They are symmetrical, so you can just divide 90 by 2 who is 45 and you have to it answer.
