Answer:

Step-by-step explanation:

In parallelogram adjacent angles are supplementary

∠U +∠V = 180

9x + 15 + 6x + 15 = 180

Combine like terms

9x + 6x + 15 + 15 = 180

15x + 30 = 180

Subtract 30 from both sides

15x = 180 - 30

15x = 150

Divide both sides by 15

x = 150/15

x = 10

∠U = 9x + 15

= 9*10 + 15

= 90 + 15

∠U = 105

∠V = 6x + 15

= 6*10 + 15

= 60 + 15

∠V = 75

Answer:

second option

Step-by-step explanation:

diameter= 22 cm

radius = diameter/2

=22/2

11 cm

volume of a sphere = $\frac{4}{3}*pie* r^3$

= $\frac{4}{3} * 3.14 *11^3$

=4.186666 * 1331

=5572 . 5 cubic centimeters (cm^3)

Which is the directrix of a parabola with equation x^2=8y

stellarik [79]

According to the definition, is a parabola is in the standard form of (x-h)^2<span>=4p(y-k), then the directrix is y=k-p. In this case, the parabola function is x^2=8y, so h=0, p=8/4=2, k=0. Plug the values of h, p, k, into y=k-p, the directrix is y=-2.</span>

How do i solve 1+1=0

tia_tia [17]

Answer:

Logically that's not possible but if you want to prove it then, you have to use a trick.

Step-by-step explanation:

1 + 1 = 1 + $\sqrt{1}$

= 1 + $\sqrt{(-1) * (-1)}$

= 1 + $\sqrt{(-1)}$ * $\sqrt{(-1)}$

= 1 + $\sqrt{i^2}$ * $\sqrt{i^2}$

= 1 + i * i

= 1 + i^2

= 1 + (-1)

= 1 - 1

= 0

So, 1 + 1 = 0

Hope this will help. Please give me brainliest.
