Step-by-step explanation:
This time round, use SOH method (Sin angle = Opposite/Hypotenuse)
given Opposite = 7
Hypotenuse = 10

The parking lot is 14 yards long by 7 yards wide.
A = W x L The formula is ....
L = W + 7 The problem tells us that ...
A = W (W + 7)
A = w^2 + 7w
98 = w^2 + 7x
... continue from there
Answer:
y = -3x+8
Step-by-step explanation:
formula = y=mx+b
slope is m
y-intercept is b
Answer:
25 cm^2
Step-by-step explanation:
The side length of square 1 is sqrt(169) = 13
The side length of square 2 is 48/4 = 12
From the Pythagorean Triple 13 - 12 - 5, the side length of square 3 is 5
Finally, 5 * 5 is 25
