Complementary is which add up to 90 °
8)
59+31=90° complementary angles.
supplementary is which add up to 180°
10) 156+24=18 supplementary angles
12)
shows right angle=3x+45=90
3x=45
x=15°
14) supplementary angles
2x+3x+25=180
5x+25=180
x=31°
16) again it makes supplementary angles
x+2x+21=180
3x+21=180
x+7=60
x=53°
Answer:
6082.70
Step-by-step explanation
15300 × .8575 × 8575 × .8575 × .8575 × .8575 × .8575 = 6082.69727735
6082.69727735 rounds to 6082.70
Parallel is the answer
Perpendicular and intersecting lines both have and intersection point
Skew lines don't interest but they are not coplanar
1 lb is equal to 16 oz
so you would do 16*9 which equals 144.
9 lb= 144 oz
Side1 + side2 + side 3 = 84
side1 is the shortest side, and its length is x.
side2 is the middle side, and its length is x + 7
side3 is the longest side, and its length is 2x - 7
x + x + 7 + 2x - 7 = 84
4x = 84
x = 21
side1 = x = 21
side2 = x + 7 = 21 + 7 = 28
side3 = 2x - 7 = 2(21) - 7 = 42 - 7 = 35
The length of the sides are 21 m, 28 m, and 35 m.
