Brainliest answer.. . the expression (3x+5) and (4x-4) represent the measures of two angles of a regular nonagon. find the measure of an angle of the nonagon. i'm not sure if you need this information to solve, but the inside of a nonagon should equal 1260 degrees.

To extend that further, if the polygon has x sides, the sum, S, of the degree measures of these x interior sides is given by the formula S = (x - 2)(180).

For example, a triangle has 3 angles which add up to 180 degrees. A square has 4 angles which add up to 360 degrees. For every additional side you add, you have to add another 180 degrees to the total sum.

Quadrilateral ABCD has, of course, four angles. Those four angles are in the ratio 2:3:3:4. Find the degree measure of the biggest angle of quadrilateral ABCD.

2x + 3x + 3x + 4x = 360 
12x = 360 
x = 360/12 
x = 30

Even though we know x = 30 we aren't done yet. We multiply 30 times 4 to find the biggest angle. Since 30 times 4 = 120, the biggest angle is 120 degrees. Likewise, the other angles are 3*30=90, 3*30=90, and 2*30 = 60.

what golf ball

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
