Answer:
Its the first answer choice, basically just plug 3a +1 for a and solve
That's accurate, but what help do you need?
Answer:
tanΘ = - 
Step-by-step explanation:
Given
cosΘ =
= 
The right triangle has sides 7, 24, 25 ← Pythagorean triplet
with adjacent = 7 and opposite = 24
Since position is in fourth quadrant then tanΘ < 0 , thus
tanΘ = - 
Answer:
The rug is two feet too wide
Step-by-step explanation:
Well first, let's figure out the diameter of the rug to see if it will fit in the room. We know that the circumference of the circle is πd. So we can solve for d from there (d is the diameter).
c = πd
50.24 = πd
50.24/π = d
d = about 16 ft
Knowing this, we know that the rug would not fit in the room and if it was centered, it would have a foot of rug sticking out from each wall. Therefore, the rug is two feet too wide.
