A 100-foot ramp is tilted at a 45° angle. How high is the top of the ramp from the ground?

BabaBlast [244]

Setting up a right triangle, the 100 would be the hypotenuse, the 45 would be the angle of elevation, and you're looking for the opposite side.
Sin 45 = x/100
100sin45 = x
100 * ✓(2)/2 = x
50 ✓2 =x
x = 50✓2 ft

I need help with this question I’m stick

bonufazy [111]

Answer:

4.8 (you can check but that's what I got)

Step-by-step explanation:

First find the missing angle by subtracting the sum of the two given from 180°

$180-(47+90) =$ 43°

Then use the Law of Sines to find the missing side

x/sinC = a/sinA

x/sin(90°)/3.5/sin(47°)

x=sin(90°)×(3.5/sin(47°))

x=4.7856...

x ≈ 4.8
