We notice a factor of 2x in both
2x(5x^2+4x-3)
trial and error
(5x-3)(x+1) yeilds 5x^2+2x-3, nope
(5x+3)(x-1) yeilds 5x^2-2x-3, nope
(5x-1)(x+3) yeilds 5x^2+14x-3, nope
(5x+1)(x-3) yeilds 5x^2-14x-3, nope
simplest form is
2x(5x^2+4x-3)

Answer:
x° ≈ 50.0°
Step-by-step explanation:
The sides adjacent and opposite the angle are given. The appropriate trig relation is ...
Tan = Opposite/Adjacent
tan(x°) = 50/42
The inverse function is used to find the angle whose tangent is a particular value:
x° = arctan(50/42) ≈ 49.9697°
x° ≈ 50.0°
