Step-by-step explanation:
Hey there!
The given midpoint is; X(-8,4) and G(2,-9).
To find: H
Now; You need to use formula for midpoint.

I'll tell you how to find the answers and just use the give angle measure to solve.
9) angle 11 = angle 14
10) angle 9 + angle 15 = 180
11) angle 10 = angle 3
12) angle 7 = angle 14
10 times 0.84 is 8.4 or 8.40 is completely fine as well.
Answer:
$14.28
Step-by-step explanation:
If the CD is $17 and is have a 20% off then you multiply .20 and 17 to get the amount that is off. Subtract that answer from 17 and you should get $13.60. That is the cost of the CD WITHOUT tax. To apply the tax, you multiply the cost and 0.05 (5%) to get 0.68. 0.68 is the tax cost. To get the entire cost of the CD, you add 0.68 (tax) and price (13.60) and get $14.28.

Determine the length of the legs
To do this, we apply Pythagoras theorem.
In this case:
Open Bracket
Collect Like Terms
Solving using quadratic formula:
So:
or 
Since, x can't be negative, then:
One of the leg is:
