Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
sin(D) = 20/29
D = arcsin(20/29)
D=43.60281897 °
cos( 43.60281897 °)= DF / 29
DF = 29*cos( 43.60281897 °)
DF = 21
sin(D) = 20/29
cos(D) = 21/29
tan(D) = 20 / 21
sin(E) = 21/29
cos(E) = 20/29
tan(E) = 21 / 20

Answer:
y = (-3/5)x + 4
Step-by-step explanation:
Parallel lines have the same slope.
So the slope to the other line would be -3/5 as well.
Slope-intercept form is y = mx + b where m is the slope.
So you substitute the slope in making it y = (-3/5)x+b.
To find b, the y-intercept, you have to plug in the point for y and x in it. So you use the point (5,1) for it. That would get to 1 = (-3/5)5 + b.
To simplify that, it would get to 1 = -3 + b
Then you add 3 on both sides getting to b = 4.
Then you substitute b in, getting y = (-3/5)x + 4.
