Step-by-step explanation:
Triangle CDE is a right angle triangle.
From the given right angle triangle
CE represents the hypotenuse of the right angle triangle.
With ∠C as the reference angle,
CD represents the adjacent side of the right angle triangle.
DE represents the opposite side of the right angle triangle.
To determineTan C, we would apply trigonometric ratio
Tan θ = opposite side/adjacent side. Therefore,
Tan C = 80/39
Tan C = 2.0513
Rounding up to the nearest hundredth, it becomes
2.05

Answer:
Step-by-step explanation:
The two x intercepts are
x - 7 = 0
x = 7
x + 3= 0
x = - 3
The y intercept is just - 7 * 3 = - 21
To prove this more formally
f(x) = (x - 7)(x + 3)
f(x) = x^2 - 7x + 3x - 21
f(x) = x^2 - 4x - 21
