Using the Pythagorean theorem
c^2 = a^2 +b^2
C^2 = 12^2 + 8^2
c^2 = 144 +64
c^2 = 208
c= sqrt(208)
c= 14.4 feet

65 cents
Step-by-step explanation:
4.55/7=.65
Since you are in middle school, I will assume simple shapes such as rectangles and squares
area=legnth times width
therefor
width=area/legnth and
legnth=area/width
So listen to your teacher next time
Answer:
yes, it is a right triangle and ∡Q is the right angle
Step-by-step explanation:
if the slope of QR is the opposite reciprocal of QS then the two segments are perpendicular and form a 90° angle
slope of QR: -3 - (-1) ÷ 2 - 0 = -2 ÷ 2 = -1
slope of QS: -3 - (-1) ÷ 2 - 4 = -2 ÷ -2 = 1
-1 and 1 are opposite and reciprocal so m∡Q = 90°
