The vase of the triangle would be x because it is unknown and the height would be x+2 because it is 2 more units than the base the formula for the area of a triangle is (base)(height)% 2 =area so (x)(x+2)%2=12 so then you have 1/2x^2+x=12 at this point I would move the 12 to the other side by subtracting to get 1/2x^2+x-12=0 then I would multiply it all by 2 to get x^2 + 2x-24 from there I would factor to get (x+6)(x-4) and your answers would be x= -6 and 4 and because 6 is negative it would not work because distances are always positive so the base would equal 4
1 hour = 70 miles
3 hours = 70 x 3
= 210 miles
The answer would be 210 miles.

Answer:
A. X = 30º
Step-by-step explanation:
The angle labeled x & the right angle are vertical angles to the one labeled 120º.
Therefore:
X + 90 = 120
Solve for x:
X + (90-90) = 120 - 90
X = 30
Hope this helps! Have a great day!
