What is the surface area of this square pyramid?
Karo-lina-s [1.5K]

Answer:

A;3600 yd2

Step-by-step explanation:

The surface area is found by adding the area of the sides

The area of the bottom is

A= s^2 where s is the side length since it is a square

A = s^2 = 30^2= 900

We can find the area of one of the sides and multiply by 4 since all the sides are the same

The sides are triangles so

A = 1/2 bh  where b is the base b=30 and h is the height = 45

A = 1/2 (30)* 45

A = 675

We have 4 of these triangles

4*675 =2700

Add the 4 triangles and the bottom

2700+900

3600

The length of two complementary angles are x and 2x+12. Find the measures of the angles.
Shtirlitz [24]

There's no such thing as the "length"of an angle. 
But we know what you're getting at.

You have said that the angles are complementary.  If two angles are
complementary, then  their sum is 90 degrees, so we can take your
two angles and write:

                       <u>x</u>  (one angle) plus <u>(2x + 12)</u> (the other one) <u>= 90 degrees

</u>
<u />                          x + 2x + 12  =  90<u>

</u>
Subtract 12 from each side:     x + 2x  =  78

Add the x's on the left side:        3x      =  78

Divide each side by  3 :                x      =  26 degrees

One angle is 'x'  =  <em>26 degrees</em>

The other one is (2x + 12) = 52+12 = <em>64 degrees</em>
