Astatue is mounted on top of a 42 foot hill. from the base of the hill to where you are standing is 73 feet and the statue subtends an angle of 10.3° to where you are standing. find the height of the statue.

  19.72 ft

Step-by-step explanation:

You know the tangent of an angle is the ratio of the opposite side to the adjacent side of the right triangle. So, the angle α to the bottom of the statue is ...

  tan(α) = (42 ft)/(73 ft)

  α = arctan(42/73) ≈ 29.914°

Then the angle to the top of the statue is ...

  β = 10.3° +29.914° = 40.214°

The same tangent relationship tells us the height to the top of the statue from the base of the hill is ...

  tan(β) = (height to top)/(73 ft)

Multiplying by 73 ft gives ...

  height to top of statue = (73 ft)·tan(40.214°) = 61.72 ft

So, the height of the statue is the difference between the heights of its top and its base:

  statue height = 61.72 ft - 42 ft

  statue height = 19.72 ft

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
