Answer:

x=5

Step-by-step explanation:

The sum of the interior angles of a polygon is found by

(n-2)*180 where n is the number of sides

There are 6 sides

(6-2) *180

4*180

720

The sum of the angles is 720

18x+25x+28x+26x+29x+90=720

Combine like terms

126x +90=720

Subtract 90 from each side

126x +90-90=720-90

126x =630

Divide by 126 on each side

126x/126 = 630/126

x=5

Answer:

5

Step-by-step explanation:

This is a hexagon (6 sides)

Total angle should be:

(6 - 2)(180) = 720

In terms of x:

Total angle = 126x + 90

720 = 126x + 90

x = 5

HELP ME PLEASE ASAP<br> IT IS A CLOCK PROBLEM<br> What is the angle between the hands at 4:41?
qaws [65]

Answer:127.5∘

Step-by-step explanation:

The angle measure between any two consecutive numbers on a clock is 36012=30∘.

Call the "12" point on the clock the zero-degree point.

At 4:45, the minute hand is at the "9" - that is, at the 30×9=270∘ mark. The hour hand is three-fourths of the way from the "4" to the "5; that is,

30×434=142.5∘ mark.

Therefore, the angle between the hands is

270−142.5=127.5∘, the desired measure.
