Find the perimeter and area of the polygon shown below. The polygon is a trapezoid made up of a rectangle and a right triangle.

algol13

Since, the polygon is a trapezoid made up of a rectangle and a right triangle. Therefore, according to the question, the figure of the polygon is attached.

Since, perimeter is the total length of the outer boundary of the figure. Therefore,

Perimeter of the polygon is $=AB+BE+ED+DC+CA$

$=18+17+8+18+15$

$=76 \ ft$

Area of the polygon = Area of Rectangle + Area of Triangle

$=[(18) \times (15)] + [(\frac{1}{2}) \times (8) \times (15)]$

$=270 + [(\frac{8}{2}) \times (15)]$

$=270 + [4 \times (15)]$

$=270 + 60$

$=330 \ {ft}^{2}$

there are 640 students in one school. How many boys are there if it is known that 1/4 of the number of girls is equal to one six

Anna007 [38]

Answer:

960

Step-by-step explanation:

You have to figure out what 1/4th of 640 is, which is 160.

It says that number is 1/6th of boys, so you multiply by the inverse.

160x6 = 960

What’s the measure of the angle theta?

11111nata11111 [884]

Answer:

∅ = 50°

Step-by-step explanation:

YOU NEED A CALCULATOR TO SOLVE THIS!

You need to use Law of Sines

$\frac{a}{sinA} =\frac{b}{sinB} = \frac{c}{sinC}$

Here you will be doing $\frac{a}{sinA} =\frac{c}{sinC}$

a and c are the lengths, while A and C are the angles

$\frac{3.46}{sinA} = \frac{2.54}{sin43}$ you want to get the denominators out from underneath so multiply both sides by sinA and sin43

$3.46sin43 = 2.54sinA$

Now you want to get sinA alone so divide both sides by 2.54

$\frac{3.46sin43}{2.54} = sinA$ now get A alone

$sin^{-1} (\frac{3.46sin43}{2.54}) = A$ put that into the calculator

$49.61741033 = A$
