4. A house is 5.8 m wide. The roof is being designed by an architect so that one side will be longer in order to accommodate solar panels. If the angle at the rooftop is to be
110°, and the angle of elevation of the shorter side is to be 45°, find the lengths of the
rafters needed to support each side of the roof.

ask the math teacher she or he would know lol.

step-by-step explanation:

60 for the first and 130 for the second

step-by-step explanation:

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
