1. The cross section of an A-frame cottage is an isosceles triangle. If the slope of one of the sides is 1.8 and it is 19 feet high at the peak, what angle

does the side make with the horizontal? What is the width of the cottage?

21.12

Step-by-step explanation:

To solve this, it's best to use Cartesian planes. So we draw it in the Cartesian planes. From the question, we have {0, 19} and also {1.8, 0}.

If x = -1.8 and x = +1.8, then

1.8 = (19 - 0) / (0 - x)

1.8 = 19 / -x

x = -19 / 1.8

x = -10.56

Since we're having it in 2 quadrants then, we have 10.56 + 10.56 = 21.12 to be our width of the cottage

answer is c

step-by-step explanation:

b.an increase in a causes b to decrease
