Find the value of c using the diagram below
vesna_86 [32]

Check the picture below.


notice that 146° is sitting on a flat-line, and thus it has a sibling linear angle, namely 34°.

now, recalling that a triangle has a sum of 180° for all interior angles, the missing one is 126°, and incidentally that is a corresponding angle with "c".

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)
