Answer:

x = 79 y = 22

Step-by-step explanation:

x would be the same as the other side so 79 * 2 would be 158. A whole triangle is 180. 180 - 158 = 22

Solve for e. T=e29<br><br><br> ​​ e=±3T√T<br><br> e=±3T<br><br> e=±3T√<br><br> ​ e=±9T√ ​
Anon25 [30]

Answer:

option (3) is correct.

e= \pm 3\sqrt{T}

Step-by-step explanation:

Given T=\frac{e^2}{9}

We have to solve for e.

Consider the given statement,

T=\frac{e^2}{9}

Cross multiply, we get,

\Rightarrow 9T={e^2}

Taking square root both sides , we get,

\Rightarrow \sqrt{9T}=e

We know square root of 9 is 3.

\Rightarrow \pm 3\sqrt{T}=e

Thus, option (3) is correct.

e= \pm 3\sqrt{T}

If point W is -4,-2 and point V is -2,-2 what is the length of VW
Helen [10]

Answer:

2 units

Step-by-step explanation:

The length of VW is just the distance between the two coordinates. You could use the distance formula, or an easier and faster way would be to recognize that since both points have the same y-coordinate, the distance between them will just be the distance of the x-coordinates. The absolute value of -4 and -2 is 2, so the length of VW is 2 units.

Hope this helped! ;)
