From the question we are told that:
Angle of F 
Length of 
Length of 
Generally the equation for Angle D
is mathematically given by
Since
.The triangle is a right angle Triangle
Therefore




Answer:
1. C
2. C
Step-by-step explanation:
1. 5x+12=57
Subtract 12 from both sides
5x=45
Divide both sides by 5
x=9
2. 7-4x=12-3x
Combine like terms =
-4x+3x=-12-7
x=-12-7
x=19
Answer:
y=-4x-8
Step-by-step explanation:
use points (0,-8) and (-2,0) and plug into slope formula.
slope formula=(y2-y1)/(x2-x1)
(0-(-8))/(-2-0)=-4
you get y=4x+b
use point (-2,0) to find b
you get y=-4x-8
C = 150000 + 17n
where,
C = Total Cost per year = Fixed Cost + Variable Cost
n = Number of Widgets produced each year
17n = Variable Cost
150000 = Fixed Cost
