62.5% of 56 is 35
Divide 35 and 56:
Convert the decimal to a percentage:
A point in the form of (0, number) is the y - intercept. That's because there is movement in the x -direction and the point is plotted on the y -axis. Our number in the ordered pair is the y-intercept - in this case, 10.
Slope intercept form is y = mx + b where m is the slope and b is the y-intercept. We are told the slope is 9 and we found the y-intercept, 10. 9 goes in for m, 10 goes in for b.
Thus the line (in slope intercept form) is y = 9x + 10.
Answer:
a) 150°
b) 30°
Step-by-step explanation:
It is easier to work the exterior angle first.
<h3>b)</h3>
The sum of exterior angles is 360°. The exterior angle at any vertex of a regular dodecagon will be 1/12 that:
360°/12 = 30° . . . the measure of one exterior angle
__
<h3>a)</h3>
The measure of an interior angle will be the supplement of the adjacent exterior angle.
180° -30° = 150° . . . the measure of one interior angle
1476.66 is the surface area
