The angles of a triangle will always add up to be 180 degrees total.

x + 82 + x + 82 + 40 = 180
2x + 164 + 40 = 180
2x + 204 = 180
Subtract 204 from both sides.
Think of it as “180 + (-204)”
2x = -24
Divide each side by 2.
x = -12

Answer: x = -12

To complete the container label, Gordon needs to know the lateral surface area of the container. The lateral surface area is fou
Llana [10]

Based on the radius of the container's base, and the slant height, the lateral surface area would be 21.23 in².

<h3>How can the lateral surface area be found?</h3>

= π x radius x slant height

The slant height is:

Cos BAC = BA / Slant height or AC

Cos 72° = 2 / AC

AC = 2 / Cos 72°

= 6.47 inch

The lateral surface is:

= 22/7 x 2 x 6.47

= 40.67 inch²

First part of question:

Gordon works for a graphic design firm and is creating a label for a food truck vendor. The vendor specializes in finger food and wants to sell food in right conical containers so they're easy for people to hold. To complete his label, Gordon needs to collect several different measurements to ensure that the label he designs will fit the surface of the container. Gordon has been given a model of the container and told that the diameter is 4 inches and the measure of angle BAC in the model is 72°.
