Answer:

9)=95°

10)=120°

Step-by-step explanation:

9) = 10x+5 = -4+11x - vertically opposite

or, 5+4 = 11x-10x

or, x = 9

now

10x+5

= 10*9+5

= 90+5

= 95

9)= 95°

10)= soln

16x-4+31x-4=180-being cointerior

or, 47x-8=180

or, 47x= 188

so, x = 4

now

31x-4

= 31.4-4

=124-4

=120

10)=120°

Using 3.14 for 7, a sphere has a volume of 904.32 mm.

Alla [95]

Answer:

$v = \frac{4}{3} \pi {r}^{3 } \\ 904.32 = \frac{4}{3} \times 3.14 \times {r}^{3} \\ {r}^{3} = \frac{3 \times 904.32}{4 \times 3.14} = 21.57 \\ r = 2.78$

then Radias equal to 5.5676
