Answer:

Sum of the interior angles of a regular polygon is given by = (n-2)180°

where n is the no. of sides.

In the above figure, n= 10

Therefore, sum of the interior angles = (10-2)×180°

= 8×180°

= 1440°

Measure of each angle = 1440/10= 144°

Therefore, 10x+4=144

=> 10x= 140

=> x= 14

sweet-ann [11.9K]

Answer:

Orange, Green, Red, Blue

Step-by-step explanation:

1st equation

When x = 0,  -2 raised to the 0 power is -1 so y would be -1.

When x = 1, the exponent would be -1.  -2 to the power of -1 is the inverse of -2 which is - 1/2.

The only colored graph that has points at (0, -1) and (1, -1/2) is the orange graph.

2nd equation

When x = 0, 2 raised to the 0 power is 1 so y=1

When x =1, 2 raised to the power of 1 is 2 so y = 2

The graph that has points at (0, 1) and (1, 2) is the green graph

3rd equation

When x = 0, 2 raised to the -0 power is still equal to 1 so y would be 1.

When x = 1, 2 raised to the -1 power is the inverse of 2 which is 1/2.

The only graph with coordinates (0, 1) and (1, 1/2) is the red graph

4th equation

Only color left is the blue graph but the same concept can be used.

slamgirl [31]

Answer:

8. the length is 88/5cm or 17.6cm

Step-by-step explanation:

8.perimeter =2L + 2W

when you convert the width 42/5 = 8.4

so 52 = 2L + 2*8.4

52= 2L + 16.8

52 - 16.8 = 2L

35.2 = 2L

divide both sides by 2

L = 17.6cm
