They are always supplementary.
That means their measures always add up to 180 deg.
If they both measure 90 deg, then they are also congruent, but they do not have to be congruent.
Answer is b) sometimes.
25/5 would be 5
and in the inequality, it says the d/5 is greater than 28
d=25 is nor a solution to the in equality
Answer:
55.5
Step-by-step explanation:
answer is 55.491477012331599 which rounded to the nearest tenth is 55.5
when you said to the nearest tenth of degree i assume that meant like rounding to the nearest tenth
P = 2(L + W)
P = 96
L = 2W + 8
96 = 2(2W + 8 + W)
96 = 2(3W + 8)
96 = 6W + 16
96 - 16 = 6W
80 = 6W
80/6 = W
40/3....or 13 1/3 ft <== width
L = 2W + 8
L = 2(40/3) + 8
L = 80/3 + 8
L = 80/3 + 24/3
L = 104/3 or 34 2/3 <== length
We are given with two equations and is asked to determine the solution of the system of linear equation. via elimination, we add the two equations to eliminate 3x, this means y should be equal to 9 and from the first equation, x should also be equal to 9, too
