Answer:
280
Step-by-step explanation:
30/100 = 84/x
84 x 100 = 8400
8400/30 = 280
X, 2x, and (x+2x)=3x
6x=180
x=30
30, 60, 90 triangle.
Answer:
56 meters
Step-by-step explanation:
diameter = 2(radius)
2 x 28 = 56
Equation: B/24 · 2. I hope that helps!
(x-3)^2 + (y+5)^2 = 25
remove the ^2's from the left side:
(x-3) +(y+5) = sqrt(25)
(x-3) +(y+5) = 5
radius = 5
now solve for zero 's on the left side:
x-3 = 0 x = 3 (3-3=0)
y+5 = 0 y = -5 (-5 +5=0)
so center = (3,-5) and radius is 5
Answer is last one.
