Hey there!!
(1) Both the angles sum up to be 180.
(2) Both the angles sum up to be 90
_________________
(1) 4x+5+8x-5=180
... 12x=180
... x= 180/12
... x = 15
________________
(2) 4z+3z+6=90
... 7z+6=90
... 7z=84
... z=84/7
... x=12

- Midpoint Formula:

Step-by-step explanation:
<u>Step 1: Define</u>
Point (2, 9)
Point (8, 1)
<u>Step 2: Identify</u>
(2, 9) → x₁ = 2, y₁ = 9
(8, 1) → x₂ = 8, y₂ = 1
<u>Step 3: Find Midpoint</u>
Simply plug in your coordinates into the midpoint formula to find midpoint
- Substitute in points [Midpoint Formula]:

This may not be correct but Georgia will be about nine if u subtract 6 from 15... And as for Jerry, if he swims for 4 hours, at 2 miles, he might be swimming 480 miles.. 2x60 (aka and hour x 2) 120.. Do that 4 times and u end up with about 480.. So sorry if I'm wrong
