Answer:
B: 22.5 degrees
Step-by-step explanation:
The interior angles of a pentagon add up to 540 degrees
(if you dont believe me you can turn a pentagon into three triangles, 3x180 = 540)
So you have four same angles say measure "x" degrees, and one final one that measures "5x" degrees, so 9x = 540, and x = 60
Unless I read the problem wrong, 60 degrees is the answer which is not an option :P
Edit: Yea I read it wrong, the final angle is 5 times the other four angles COMBINED, so that angle measures "20x" degrees.
The total would be 24x = 540, and so x = 22.5
Answer:
20 cm.
Step-by-step explanation:
In order to find the height, we need the volume and the base area first. We are already given the volume so we need to find the base area.
A = 18 · 5 = 90
Now that we know the base area is 90 cm², we can substitute the information into the equation to solve for the height.
V = 1/3(A)(h)
600 = 1/3(90)(h) (Given)
600 = 30h (Simplified)
20 = h (Divided 30 on both sides)
Therefore, the height is 20 cm.
Answer:
e) 14mn.
Step-by-step explanation:
The GCF of 14, 56 and 28 is 14,
The GCF of m, m^2 and m^3 is m.
The GCF of n, n^2 and n^3 is n.
The answer is therefore 14mn.
