Find the measures of two complementary angles if the difference in the measures of the two angles is 14
ira [324]
Complementary angles are angles that measure up to 90 degrees.

To find the measures of the two angles, divide 90 by two to say two angles of 45 degrees. Now divide 14 by 2, which you get 7 with. Now add 7 to 45 and subtract it from 45 as well, to get 52 and 38.

The measures of the angles are 52 degrees and 38 degrees.

a concrete pillar has the shape of a cylinder. it has a diameter of 6 meters and a height of 7 meters. concrete cost $116 per cu
GrogVix [38]

Answer:

The cost of the pillar is $22,947.12

Step-by-step explanation:

Diameter of the pillar = 6m

Radius = diameter / 2 = 6 / 2 = 3m

Height if the pillar = 7m

Volume of the pillar = πr²h

π = 3.14

V = 3.14 × 3² × 7

V = 3.14 × 9 × 7

V = 197.82m³

Volume of the pillar is 197.82m³

If 1m³ = $116

197.82m³ will cost $x

X = (197.82 × 116) / 1

X = $22,947.12

The cost of the pillar is $22,947.12

For* 15-16 find the number of sides if a polygon has the given measure for each interior angle,
salantis [7]

Answer:

15. d) 36

16. b) 20

17. d) 180

18. b) 50

19. c) 360

20. b) 60

Step-by-step explanation:

To find the number of sides a polygon has giving an interior angle, use the equation:

(number of sides - 2)*180/(number of sides) = measure of interior angle

<em>15. </em>(n = number of sides)

((n-2)*180)/n = 170

180n-360 = 170n

10n = 360

n = 36 (d)

<em>16.</em> (n = number of sides)

((n-2)*180)/n = 162

180n-360 = 162n

18n = 360

n = 20 (b)

<em>17.</em> The sum of the interior angles of a triangle is always 180 (d)

<em>18.</em> 180-60-70 = 50 (b)

<em>19.</em> The sum of the interior angles of a quadrilateral is always 360 (c)

<em>20.</em> 360-120-90-90 = 60 (b)
