Hi there!

<u><em>FACT</em></u><em>:</em>

<em>What you have there is an equilateral in which all three internal angles are congruent to each other and are each 60°.</em>

<u>STEPS TO ANSWER:</u>

I'm not really sure if you are looking for the value of "X" the angle or the value of "x" that is part of the expression that represents the value of the angle "Z".

1. If you are looking for the value of "X" the angle, it's pretty easy knowing that all internal angles are equal to 60°.

Your answer for the value of "X" the angle would be : X = 60°.


2. If you are looking for the value of the "x" that is part of the expression that represents the value of the angle "Z", you'll need to write this expression as equal to 60 and solve the equation by isolating "x" :

2x <u>- 4</u> = 60

Add 4 on each side of the equation → 60 + 4 = 64

<u>2</u>x = 64

Divide each side of the equation by 2 → 64 ÷ 2 = 32

x = 32

Your answer for the value of the "x" that is part of the expression that represents the value of the angle "Z" would be : x = 32.


There you go! I really hope this helped, if there's anything just let me know! :)

What is the surface area of this rectangular pyramid?
Alexxx [7]

Answer:

304m^2

Step-by-step explanation:

First find the surface area of the base by multiplying the length by the width.

(12m) (8m)= 96m^2

Second, find the surface area of the front and back triangles using the formula <em>1/2 (base) (height)</em>. Use the length for the base.

1/2 (12m) (10m)= 60m^2

Next, find the surface area of the side triangles using the formula <em>1/2 (base) (height). </em>Use the width as the base.

1/2 (8m) (11m)= 44m^2

Last, add the surface area of each section. Make sure you add the area of each face.(we only solved for 1 of the front/ back triangles and 1 of the side triangles) To make it easier to understand I wrote out an equation to show how I added the surface areas.

base=a, front/ back triangles= b, side triangles=c

SA= a + 2b +2c  or SA= a +b +b +c +c

Using one of the equations above solve for the total surface area.

SA= (96m^2) + (60m^2) +(60m^2) +(44m^2) +(44m^2)

or

SA= (96m^2) + 2(60m^2) +2(44m^2)

SA=  (96m^2) +(120m^2) +(88m^2)

SA= 304m^2
