7 hundred sixteen and eight hundredths (aka 716.8)
Just do 3x+5+2x=90 And solve for x.
So, 5x+5=90
5x=85
x=85/5 = 17
now you know the value of x, so you can calculate the angles.
Btw the total angle of a triangle is 180, and since this is a right angle triangle, you know that the two angles added together needs to equal 90.
Answer:
Ryan earns more per hour.
Step-by-step explanation:
1) 40/5=$8.00 per hour for jamie
2)8.50/1=$8.50 per hour for ryan.
3)8.50>8.00
Let width = x
Let length = 2x + 11
Area = 63 ft2
length × width = Area
x(2x + 11) = 63
2x2 + 11x = 63
Subtract 63 on both sides of equation.
2x2 + 11x - 63 = 0
Factor the left side of equation.
(2x - 7)(x + 9) = 0
x = 7/2 and x = -9
Since the dimensions cannot be negative, we accept the positive value of x: x=7/2. Substitute this value of x into the dimensions
width = 3.5 ft
length = 2(3.5) + 11 = 7 + 11 = 18 ft
