Step-by-step explanation:
3x + 1 + 5x + 2 = 3x + 5x + 1 + 2
= 8x + 3
add the like terms. Here like term are 3x and 5x ie have same variable

Howard is 155.1 yards from the top of the water reservoir.
Step-by-step explanation:
A right angle triangle is formed. The distance between Howard and the bottom of the reservoir represents the adjacent side of the right angle triangle.
The distance of Howard from the top of the reservoir, h represents the hypotenuse of the triangle.
To determine h, we would apply
the cosine trigonometric ratio.
Cos θ = adjacent side/hypotenuse. Therefore,
Cos 55 = 89/h
h = 89/Cos 55 = 89/0.574
h = 155.1 yards
