Answer:
21/20, or 1.05.
Step-by-step explanation:
In this case, the measure of angle R is the same as angle V.
To find the tangent of a triangle, you do opposite over adjacent.
So, the tangent of angle V is 21 / 20.
That means that tan(R) = 1.05.

I think the answer is -7x(-7)x(-7)
<span>The constant rate of change is 30 seconds because:
1 mile=30 seconds
2 miles=1 minute
3 miles=1 minute and 30 seconds
4 miles=2 minutes
5 miles=2 minutes and 30 seconds
or in other words 2.5</span>
1+(1*4)=5
2+(2*5)=12
3+(3*6)= 21
5+(5*8)=45
Hope this helps
