Answer:
they are acute
and are also equivalent
that's the relation in the 2 angles
To find the area og a trapezoid: (base 1+ Base 2)h divided by 2
Answer:

Step-by-step explanation:
The formula to find the error is:

Where:
is the standard deviation
n is the sample size
So
n = 80 people
= 12 movies
Then
= confidence level = 0.99


We look for the Z value: 
Looking in the normal standard tables
Therefore:

Answer:
A. 2
B. 84
C. 18
Step-by-step explanation:
A. y ÷ 2 + x = 2 ÷ 2 + 1
= 1 + 1
= 2
B. z(x +y) = 6(6 + 8)
= 6(14)
= 84
C. 6q + m - m = 6(3) + 3 - 3
= 18 + 3 - 3
= 21 -3
= 18
