Answer:
34 inches
Step-by-step explanation:
A doormat is the shape of a rectangle and its area uses A=l*w. If the area is 714 and its length is 21, then 714 = 21*w. Solve for w.
714=21w
714/21= 21w/21
34 = w
Since the shading on the left side, and the line goes through the x axis, your answer would be B.
<LMP and <NMP are supplementary angles so sum = 180
<LMP + <NMP = 180
(-16x + 13) + ( - 20x + 23) = 180
-16x + 13 - 20x + 23 = 180
-36x + 36 = 180
-36x = 144
x = -4
<LMP = -16x + 13 = -16(-4) + 13 = 77
<NMP = - 20x + 23 = - 20(-4) + 23 = 103
Answer
<LMP = 77°
<NMP = 103°

Step-by-step explanation:
curved surface area =
perimeter of triangular base × length
= 3×8 + 12
= 24 + 12
= 36mm^2
total surface area
= curved surface area + 2× area of triangular base
= 36 + 2 × root3 ×8^2 ÷ 4
= 36 + 2 × root3 × 16
= 36 + 2× 27.71
= 36 + 55. 425
= 91.425 mm^2
