A) Pine Road and Oak Street form a right angle, so we can extract the relation

where

is the distance we want to find (bottom side of the rectangle).
Alternatively, we can use the other given angle by solving for

in

but we'll find the same solution either way.
b) Pine Road and Oak Street form a right triangle, with Main Street as its hypotenuse. We can use the Pythagorean theorem to find how long it is.

Let

be the length of Main Street. Then

but of course the distance has to be positive, so

.
Answer:
First one: 37.5
Second one: 108
Step-by-step explanation:
For the first one:
the figure shown is a triangle
The area of a triangle can be calculated using this formula
where b = base length and h = height
The triangle shown has a height of 7.5 and a base length of 10
Using this information we plug in the values into the formula.

Hence the area of the figure is 37.5 square units
For the second one.
The figure shown is a parallelogram with a height of 9 and a base length of 12
The area of a parallelogram can simply be calculated by multiplying the base length by the height
So area = 9 * 12
9 * 12 = 108
Hence the area of the figure is 108 square units
Answer:
D
Step-by-step explanation:
If the lines are parallel, the slope of both of them are going to be the same. So if one line is 3, the other one will be too.
Answer:
<h2> $430.90</h2>
Step-by-step explanation:
Given that the principal p= $290
rate r= 2.2% 2.2/100 =0.022
time t= 18years
by applying the expression

We have

Hence after 18years the money in the account will be $430.90
