Answer:
a = 
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + 9² = 12²
a² + 81 = 144 ( subtract 81 from both sides )
a² = 63 ( take square root of both sides )
a =
Answer:
140 is the answer for y2 because x1 is 80 more than x2 so you would subtract y2 by 80
Your answer is 3277 because a negative divided by a negitive makes it a positive.
I believe the answer is 10.362
