First convert the feet to inches:

3 feet= 36 in.; 4 feet=48 in.

Make an equation for each one:

Type A: h=36+15x

Type B: h=48+10x

Since the questions wants the heights to be equal, h=h so you can substitute so you have:

36+15x=48+10x

5x=12

x=2 2/5 years or 2.4 years

You are designing a ramp where the horizontal distance is twice the vertical rise. what will be the ramp angle to the nearest te

ankoles [38]

Use the definition of tangent

or inv tangent (arctan or atan)

tan(theta) = opposite side/ adjacent side

the vertical rise would be the opposite side, the horozontal distance would be the adjacent side

let rise = y
let distance= x
x=2y

so tan(theta) = y/2y
tan(theta) = 1/2

theta = atan(1/2)

grab a handy dandy calculator, unless you know this conversion off the top of your head
