It could not be 73º because if you add that to 120 then it will be more than 180 degrees, which is the total number of degrees in a triangle. Hope this helps!

The sum of interior angles in a triangle is 180°

If an angle is 120°, then the sum of the other angles is
180° - 120°
= 60°

First, second, and third options are less than 60°. So the three choices are possible angle to the triangle.

The fourth option isn't possible for the triangle. So the answer of the question is fourth option (73°)

What is the surface area of this right prism?

Amiraneli [1.4K]

Answer:

Since the 'base' and 'top' of any prism have the same shape, the surface area can be found by

surface area of prism = 2 * area of base + perimeter of base * H

So for the rectangular prism in your example..

surface area = 2LW + 2(L+W)H

= 2 * 7 * 4 + 2*(7+4)*5

= 56 + 2 * 11 * 5

= 56 +110

= 166 sq cm

Hope this helps

Nataliya [291]

So what we do first is find out the cost per foot which is 305÷154=1.9805194805194805195
Then we find out the area of the second rug which is 288 feet and multiply that by the cost 1.9805194805194805195. We then get 1.9805194805194805195x288=570.38961038961038961
