Answer:
x = 55° (nearest degree)
Step-by-step explanation:
Trig ratios:

where
is the angle, O is the side opposite the angle, A is the side adjacent to the angle, and H is the hypotenuse of a right triangle
Given:

- A = 3.3
- H = 5.7


⇒ x = 55° (nearest degree)

Answer:
-1.25x + 0.2
Step-by-step explanation:
(-0.5x - 0.4) - (0.75x - 0.6) = -0.5x - 0.4 - 0.75x + 0.6
= -0.5x - 0.75x - 0.4 + 0.6
= -1.25x + 0.2
