Ok so first 2.4 will have to be changed to 24 which means we multiplied it by ten making it 24/10 since it is tan it is opposite side/ adjacent side so your one of your legs will be 24 and one will be 10. Now we just plug that into the Pythagorean Theorem to find the hypotenuse and we get 26. The area is 24b10/2=120 the area is 120.

Leg a= 24

Leg b= 10

Hypotenuse=26

Area=120  

Ignore my awful handwriting but this is what it looks like labeled. I made each unit=2 just so it wouldn't be as large but I hope this helps you :)

Answer:  y = 6

Step-by-step explanation:

The opposite sites of a parallelogram should be equal length. Therefore 7y = y + 36, so 6y = 36 and thus y = \boxed{6}.

In the data set below, what is the variance?
GaryK [48]

Answer:

Step-by-step explanation:

First the mean= (1+6+7+2+9)/5=25/5=5

The Variance is taking the difference by subtracting , square it, and then average the result:

1-5=-4         -4²=16

6-5=1           1²=1

7-5=2           2²=4

2-5=-3          3²=9

9-5=4            4²=16

                    Total: 16+1+4+9+16=46

Variance= 46/5=9.2
