Answer:
x=2
Step-by-step explanation:
Add all the sides to find the perimeter
x+4 + 4x+10(x-1) = 24
Distribute
x+4+4x +10x-10 = 24
Combine like terms
15x -6 = 24
Add 6 to each side
15x-6+6 = 24+6
15x = 30
Divide each side by 15
15x/15 = 30/15
x = 2
Answer:
The answer is C) y - 2 = -5/7(x - 6)
Step-by-step explanation:
Since we have the slope (-5/7) and a point (6, 2), we can just input those in for m and (x1, y1) in point-slope form.
y - y1 = m(x - x1)
y - 2 = -5/7(x - 6)

We will want to use the tangent ratio for this question. Opposite=x, adjacent=30.5. Tan(33)=x/30.5.
Tan(33)(30.5)=x
X=19.806, or rounded off x=19.81.
