b
Step-by-step explanation:
Answer: 7,-10,-2
Step-by-step explanation:
This is a right angle triangle problem
drawing a vertical line at from the point where the ramp touches the car park leaves a right angle triangle with the
opposite being 2m
hypothenus being 10m
adjacent unknown
we could use sine
SineO equal to opposite over hypothenus
SineO equal to 2/10
SineO equal to 0.2
O equal to Sine^1(0.2)
O equal to 11 .5
The angle between the ramp and the horizontal is 11.5 degrees
Answer
$79.45
Use the <em>simple interest formula</em>
A= P(1+rt)
A = 70(1+0.045×3)
And you solve, which gives you 79.45
