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

\tan30^\circ=\dfrac x{11\sqrt3}\implies\dfrac1{\sqrt3}=\dfrac x{11\sqrt3}\implies x=11

where x is the distance we want to find (bottom side of the rectangle).

Alternatively, we can use the other given angle by solving for x in

\tan60^\circ=\dfrac{11\sqrt3}x

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.

(\text{Pine})^2+(\text{Oak})^2=(\text{Main})^2

Let y be the length of Main Street. Then

(11\sqrt3)^2+11^2=x^2\implies x^2=484\implies x=\pm22

but of course the distance has to be positive, so x=22.

Answer both of the questions please :&lt;<br><br> no links!!!
SIZIF [17.4K]

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

A=\frac{bh}{2} 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.

A=\frac{7.5*10}{2} \\7.5*10=75\\\frac{75}{2} =37.5\\

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

A person places $290 in an investment account earning an annual rate of 2.2%, compounded continuously. Using the formula V = Pe^
Tomtit [17]

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

V = Pe^{rt}

We have

V = 290e^{0.022*18}\\\\V=290e^{0.396}\\\\V=290*1.48586931755\\\\V=$430.90

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