Answer:
They are triangle that have equal side and angle measurements.
Step-by-step explanation:
A = L * W
A = 44
L = 2W - 3
44 = W(2W - 3)
44 = 2W^2 - 3W
-2W^2 + 3W + 44 = 0
(-2W + 11)(W + 4) = 0
W + 4 = 0
W = -4......not this one because it is negative
-2W + 11 = 0
-2W = -11
W = -11/-2
W = 5.5 <=== width is 5.5 yds
L = 2W - 3
L = 2(5.5) - 3
L = 11 - 3
L = 8 <=== length is 8 yds
I don't really know what your talking about, so i will guess.
One angle is 54, and its complememtery is x. So, 90-54=36
x=36
Answer:
Step-by-step explanation:
Subtract 5 from each side
Youre left with: 47 (21 + 3x) = 36
Use distributive property.
47 * 21 = 987
3 * 74 = 141x
987 + 141x = 36
- 987 from each side
141x = -951
divide each side by 141
x = -6 35/47
