What is DEF ?
Is it a straight line ?
Is it a line that's bent in two places ?
Is it a triangle ?
Is there a picture ?
Do you have a drawing ?
Could you describe it for us ?
IF DEF is a triangle, then all three angles add up to 180 degrees.
The angles take 2 shares, 4 shares, and 4 shares of the 180.
There are (2 + 4 + 4) = 10 shares all together.
So each share is (180 / 10) = 18 degrees.
The angles are:
-- 2 shares = (2 x 18) = 36 degrees
-- 4 shares = (4 x 18) = 72 degrees
-- 4 shares = (4 x 18) = 72 degrees .
None of this means anything unless DEF is a triangle.
Each ticket cost 8 dollars because when you eliminate the 5v out you get 12c=246 and 6c=198 then you end up with 6c=48 and then divide to get c=8
Answer:
97
Step-by-step explanation:
83 and JKL form a straight line so they add to 180 degrees
83+ JKL = 180
Subtract 180 from each side
83-83+ JKL = 180-83
JKL = 97
Answer:
64
Step-by-step explanation:
total of a triangle adds up to 180 degrees
so:
76+37=116
180-116=64
Answer:
25
Step-by-step explanation:
8b^2 +2a(4c-b)
Let a = 1/4 b=2 c= -3
8 ( 2)^2 +2(1/4) ( 4*-3 -2)
Parentheses first
8 ( 2)^2 +2(1/4) ( -12 -2)
8 ( 2)^2 +2(1/4) ( -14)
Then exponents
8 ( 4) +2(1/4) ( -14)
Then multiply
32 -7
Subtract
25
