Answer:
if exterior angle is 10 degrees, then interior angle is 180 -10 = 170 deg.
Each trinaglke inside the polygon will be isosceles with two angles of 170/2 - 85 degrees each.
So, angle at centre = 180 -170 = 10 deg.
Ttal angle at centre = 360 deg.
No of sides = 360 /10 = 36 sided polygon.
b) Sum of interior angles is given by (2N-4) Right angles
So: 9900 = (2N-4)x90 = 180N - 360
180N = 9900 +360 = 10260
N = number of sides = 10260 / 180 = 57 sides
Answer:
0.74
Step-by-step explanation:
We can isolate x, getting 9.2x - 1.9x = -1 + 6.4
We can then simplify, getting 7.3x = 5.4, which we can solve by dividing both sides by 7.3:
x = 5.4 / 7.3 = 0.74
Johnathan works part time on weekends at the movie theater while going to school during the week. His paycheck for this pay period was $225.
When he got up to go to school Monday morning his car would not start. His dad had the car towed to the mechanic and had the car repaired. The towing bill and repair bill totaled $225.
How much did Johnathan have left from his paycheck?
$225 + (-$225) = 0
0 is the answer when you add opposites
Gravity always acts downward on every object on earth. Gravity multiplied by the object's mass produces a force called weight. Although the force of an object's weight acts downward on every particle of the object, it is usually considered to act as a single force through its balance point, or center of gravity.
Centre= (-1,-2)
Radius=5
