Find the sum of the angle measures in a regular polygon.

Answer:

D) 1260°

Step-by-step explanation:

In an n-sided polygon, the sum of all angles is equal to (n-2)*180°.

Look at it this way - let's add a point in the middle and connect it to each vertex. Then we've got n triangles for a total of n*180°, but all of the angles at the middle point aren't "part" of the polygon, so a full 360° angle should be subtracted, giving us n*180°-360° = (n-2)*180°

You can easily confirm that it works for triangles and quadrangles ;)

The figure in the picture has 9 sides, so the sum of angles is (9-2)*180° = 7*180° = 1260°

Answer:

C

Step-by-step explanation:

A triangle must have three angles that add up to 180 degrees.

40 + 70 + 65 = 175, which is not 180, so it cannot create a triangle.

The perimeter of a rectangle is 86cm. Its shortest side has a length of 16cm. State the length of the longest side.
Artyom0805 [142]

Answer: length = 27 cm

Step-by-step explanation:

Perimeter = 2(l + w)

86 = 2(l + 16)

86 = 2l + 32

86 - 32 = 2l

l = 54/2 = 27 cm.
