Answer:
The tree is 28 feet in height.
Step-by-step explanation:
This is a proportion problem. You need to keep the height of the objects on one side of the ratios and the length of the shadows on the other.
74 / x = 102/39 Cross Multiply
102x = 74*39 The inches as a unit cancel out.
102x = 2886 Divide by 102
x = 2886/102
x = 28.29 feet

Plugging in the values from the two matrices will give us the answer A
<h3>
Answer: 104 degrees</h3>
Explanation:
A trapezoid has exactly one pair of opposite sides that are parallel. We have BC parallel to AD. Angles C and D are supplementary because they are same side interior angles.
So,
C+D = 180
C+76 = 180
C = 180-76
C = 104
The answer is D, the expressions are not equivalent
<span>0.2d is the same as multiplying 20%.
However, multiplying 15d is multiplying by 1500%.</span>
It would drop by 24 degrees
3 x 8 = 24
For each hour another long way is simple just do
3 x 4 = 12 now just double it
12 + 12 = 24
