Answer: x=6, y=4
Step-by-step explanation:
substitute y with (x-2) in the 1st equation
10x-9(x-2)=24
10x-9x+18=24
x+18=24
x=6
Then use 6 for x to solve for y
y=6-2
y=4
The answer is X=5, X=-2 and x=-4
The answer is 2X because they have 2 twos in common and an X
If the result of the radical expression is a natural (whole) number
Answer:
Perpendicular = Y = 34.64 ft (Approx)
Base = X = 20 ft
Step-by-step explanation:
Given:
θ = 60°
Hypotenuse = 40 ft
Perpendicular = Y
Base = X
Find:
X and Y
Computation:
Sinθ = Perpendicular / Hypotenuse
Sin 60 = Y / 40
Perpendicular = Y = 34.64 ft (Approx)
Cosθ = base / Hypotenuse
cos 60 = X / 40
Base = X = 20 ft
