He is correct
basically you have
h times base1+h times bsae 2 all divided by 2
that equals
(hb1+hb2)/2
if we undistribute h using distributive property which is ab+ac=a(b+c)
(h)(b1+b2)/2
if you split the trapezoid in half with a horizontal line that passes through the halfway point of the height and take those two shapes and put them side by side and cut the triangles off the ends and add them, you will see why this is true
the reason is becuase you can get to the area formula from that is height times (b1+b2)/2
Answer:
540 m
Step-by-step explanation:
We are given that
Central angle,
rad
Radius of circle=18 m
We have to find the length of the arc s.
We know that
Length of arc,
Using the formula then, we get
Length of arc,
Hence, the length of arc=540 m
Answer:
Suppp. Broooo
Step-by-step explanation:
9 and 5/8, because 8 can go into 77, 9 times. That is 72 and, 77 subtract 72 is 5 so, 5/8. Then the answer would be 9 and 5/8 which is not simplified.
