Complementary angles add to 90 degrees.
Supplementary angles add to 180 degrees.
Vertical angles are equal.

So, the answers are (in degrees):

6) 47, 137, 43

7) 49, 131, 49

8) 18, 72, 18

9) 13, 77, 167

A car brought for 13000 deprecitates at 15 percent per year find value of car after 5 years

Nesterboy [21]

the value of the car will be 3250 after 5 years

Step-by-step explanation:

the value of the car = 13000

rate of interest = 15%

time = 5 years

in 5 years the car will depreciates = 13000 X 15% X 5

= $\frac{13000 X 15 X 5}{100}$

= 9750

after 5 years the value of the car is = 13000 - 9750 = 3250

The volume of a? cone-shaped hole is 49 pi ft cubed . If the hole is 3 ft? deep, what is the radius of the? hole?

lidiya [134]

$\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ h=3\\ V=49\pi \end{cases}\implies 49\pi =\cfrac{\pi r^2(3)}{3}\implies 49\pi =\pi r^2 \\\\\\ \cfrac{49\pi }{\pi }=r^2\implies 49=r^2\implies \sqrt{49}=r\implies 7=r$
