Answer:

Step-by-step explanation:

Supplementary angles are 180*

So 180+18= 198*

Supplementary angles are two angles that add up to 180°

The unknown angle is known as x

The second angle, being 18° more than the unknown angle, is x+18

So, the expression can be written as x+x+18=180

Subtract 18 from both sides.

x+x=162

Combine like terms

2x=162

Divide by 2 on both sides

162/2=81

x=81

So, one of the angles is 81°

The other is 99° ( because 81+18)

A pyramid has a square base that measures 20 inches on each side and 30 inches high. Find the volume of the pyramid.
irinina [24]

The volume of pyramid is 4000 inch³.

<h3>What is Volume?</h3>

Volume is a mathematical term that describes how much three-dimensional space an object or closed surface occupies. Volume is measured in cubic units like m³, cm³, in³, etc. Volume is sometimes referred to as capacity.

The capacity of an object is measured by its volume. For instance, a cup's capacity is stated to be 100 ml if it can hold 100 ml of water in its brim. The quantity of space occupied by a three-dimensional object can also be used to describe volume.

Given:

base = 20 inches

height = 30 inches

Now, volume of pyramid

Volume = a²h/3

Volume = 20 x 20 x 30 /3

Volume = 400 x 10

Volume = 4000 inch³

Hence, the volume of pyramid is 4000 inch³.
