Answer:

C.

Step-by-step explanation:

Recall that the sum of the (3) interior angles of a triangle <em>must</em> equate to 180.

In other words:

(55)+(20)+(x)=180

Where x is our unknown angle. So, we need to solve for x.

On the left, add 55 and 20:

75+x=180

Subtract 75 from both sides. The left side cancels:

x=105

Therefore, the third angle is 105 degrees.

Our answer is C.

The pyramid shown has a square base that is 18 inches on each side. It has a surface area of 864 square inches. What is the slan
disa [49]
The first step is to find the relationship between the square base and the surface area.

Surface area (SA) = area of the square (SS) + area of triangles.4(AT) 

Thus we can conclude area of triangles 4(AT) = SA - SS = 864 - (18*18)

4(AT) = 864 - 324 = 540

Each triangle = 540/4 = 135 square in.

An area of one triangle (AT)= (base* slant height)/2

The base = 18 in.

<span>slant height = 2(AT)/base = 2(135)/18 = 15</span>
