Answer:
9
Step-by-step explanation:
To calculate c from the first right angle triangle,
C2 = 36 + 16
C = sqrt(52)
To calculate a from the bigger right angle triangle,
B2 + 52 = (a + 4)2
B2 - a2 = -36 + 8a
A2 + 36 = B2
Solving both by elimination,
A = 72/8
=9
The answer would be letter D!
hope this helps!! pls also mark me brainliest if you can :)) i am trying to level up. thank you!!
Step-by-step explanation:
We need to factorise 3x
2
−12xy
Here we can take 3x common.
Thus we have 3x
2
−12xy=3x(x−4y)
Hence, factors are 3x,(x−4y).
Circumference = πD
45 = 3.14D
D = 14.33
Radius = Diameter ÷ 2
Radius = 14.33 ÷ 2
Radius = 7.17 ft (nearest hundredth)
--------------------------------------------
Answer: The radius is 7.17 ft.
