By using Pythagoreans Theorem: a^2 + b^2 = c^2
Easiest way to do it is add the X's together and then half it, same with the Y's.
X) -1+-6= -7 -7/2,
Y) 5+-2= 3 3/2
So the answer is B.

Answer:
Step-by-step explanation:
<u>We know that:</u>
- Angles ∠A and ∠B are 28° and 37°.
<u>We don't know:</u>
<u>So, we do this:</u>
- Add the 180°
- Solve the equation 180 - 28 - 37
<u>Solve:</u>
Angle ∠C is 115°.
75% from the original price is 51 $
p - the original price
⇒ 75/100*p=51$
p=51*100/75=5100/75=68 $
68$ - 51$=17 $
The result is 17 $
