Answer:

7y8.9 ft²

Step-by-step explanation:

Easy way:

Rotate the triangle so that the 12.1 ft side in on the bottom becomes the base.

Drop a line from the top down perpendicular to the 12.1 ft base. That makes a right triangle.

sin 71 = height/13.8

0.9455 = height/13.8

height = 13.05 ft

Area = bh/2 = (12.1)(13.05)(0.5) = 78.9 ft²

The computation of the expected rate of change in consumption is shown below:

= (Expected quadrillion thermal units - 2003 quadrillion thermal units) ÷ (difference in years)

= (563 - 421) ÷ (2015 - 2003)

= 142 ÷ 12

= 11.83

hence, the expected rate of change in consumption is 11.83

We simply applied the above formula so that the correct value could come

And, the same is to be considered
