I won't give you answers but I can tell you how to figure it out...
Let l be the length of the patio, since the area is 80 feet² we get that:
Solving the above equation for l we get:
Answer: 8.9 feet.
Interior angles of a triangle add up to 180
48 + 6x - 28 + 2x = 180
8x + 20 = 180
8x = 180 - 20
8x = 160
x = 160/8
x = 20
< A = 48
< B = 6x - 28......6(20) - 28 = 92
< C = 2x.....2(20) = 40
ANSWER
EXPLANATION
We want to solve the equation:
To do this, find the square root of both sides of the equation:
This will yield two results:
Solving the two equations, we have:
The solutions are:
