Because the area of a trapezoid is A= ((a+b)/2)h, where a is the length of the top, b is the length of the base, and h is the height, you plug that in to find your answer.
This trapezoid is sideways, but the top of it is 7m (which is a) and the base is 10 m (which is b), add a and b to get 17, A = ((17)/2)h
Now divide by 2 to get A = (8.5)h
Because the height is 9, A = (8.5)9 = 76.5
The area of the trapezoid alone is 76.5m
Answer:
Triangle ACD is similar to triangle RST
Step-by-step explanation:
In triangle ACD


In triangle RST


In triangle ACD

By triangle angles sum property
Substitute the values


Angle A=Angle R
Angle C=Angle S
Therefore, triangle ACD is similar to triangle RST
Reason:By AA similarity postulate
Answer:
Step-by-step explanation:
Notice that H is a set with 106 - 81 = 25 elements.
Hence H has
subsets.
In order to get the proper subsets of H we just need to deduct one from 
So there are
proper subsets.
Step-by-step explanation:
SinA=1/3=p/h
p=1,h=3,and b=?
Using Pythagoras Theorem,
b=√3^2-1^2
b=√9-1
b=√8=2√2
Now,
CosA=b/h=2√2/3
TanA=p/b=1/2√2
There is no phi in my keypad so I use A angle instead of phi.Adjust it.
