Step-by-step explanation:
First set both equation equal to each other since the lines are parallel means that the corresponding angles are congruent. 2x+16=3x-12 x=28 then substitute for x in the equation and they both equal 72 so that is correct but then you need to subtract 180 from 72, so 180-72=108 so the answer is 108. :) If you're wondering why subtract from 180 is bc they are supplementary meaning both angles should add up to 180

You have to get Y on a side by itsself than divide by 3 and you end up with y=-4+9x
Answer: The answer is b, 2x=14
Step-by-step explanation:
You add the equations...
2x-14=0
Move -14 over...
2x=14
Answer: D) 24 ft
Explanation:
Use the Pythagorean Theorem, a^2+b^2=c^2
So,
a^2+10^2=26^2
a^2=26^2-10^2
a^2=576
Rad a^2=rad 576
a=24 ft
