Pythagorean theorem
c2 = a2 + b2
58^2 = 42^2 + b2
3364 = 1764 + b2
1600 = b2
b = 40
Answer:
72
Step-by-step explanation:
First you do 204 - 60 = 144
Than you do 144 ÷ 2 = 72

Your answer is 3
Answer:
D.
is the correct answer.
Step-by-step explanation:
The given situation can be represented as a figure attached in answer area.
B is the base of tree.
C is the base of wires.
A and D are the end of 2 wires supporting the tree.

Here, we need to find the Height of the tree which is represented the by side AB.
and we are given that bases of wires and tree base are at a distance 4 ft.
i.e. side BC = 4 ft
If we look at the
, we are given the base BC and the
, and the perpendicular is to be find out.
We can use trigonometric identity:


Hence, D.
is the correct answer.
For 10 ream, it's cost = $49
So, for 1 ream, it would be: $49/10 = $4.9
So, your final answer is $4.9
