<h3>What is a right-angled triangle?</h3>
A right-angled triangle is a triangle with one of its angle 90°.
Analysis:
The ramp, the height of the truck bed from ground and the distance of truck bed to the point the ramp makes contact with the ground form a right angle triangle.
So that sin 30 = height of truck bed above ground/length of ramp
sin 30 = height/80
height of the truck = 0.5 x 80 = 40cm

Answer:
the last option i think so~~~
Step-by-step explanation:
It's D.
.
Why?
.
Ok, your variable is x.
.
x stands for WHAT( the VALUE ) that you want to find.
.
So, assume you know what x is.
.
Pretend it's 10 or like infinity or what-not.
.
So, x + $32.25 = $45.32.
.
But you don't know x.
.
But it's easy to find it.
.
Subtract $32.25 on both sides, and BOOM!!
.
Hope this helped!.

Any question, ASK AWAY!!
X=amount of money at first.
we can suggest this equation:
4/7 x=28
x=(28*7)/4
x=196/4
x=49
Answer: he have originally $49.
