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°
The equivalent expression to 36 + 81 is 9(4 + 9).
Sin F =9/18 = 1/2 = sin 30° (C)
I don't know the anwser sorry and what grade are u in
Simply find perimeter for fencing, which is 16+16+8+8 which equals 48. The area is needed for finding the garden area, which is 16*8, which is 128
