To calculate the exterior angle of a regular polygon, we have to divide 360 by the number of sides on the polygon
Angle a is the exterior angle on a regular hexagon, which has 6 sides.
So, to calculate the exterior angle, we use 360/6 = 60 degrees

To calculate angle b, which is an interior angle, we calculate the exterior angle and subtract it from 180. This is because angles on a straight line add up to 180 degrees

Angle b is an interior angle of an octagon, which has 8 sides. So, we use
180 - (360/8) = 180 - 45 = 135 degrees.

Hope I helped! xx

Working together, 5 friends collected 15 5/8 bags of food for the homeless. On average, how many bags of food did each friend co
Effectus [21]

15 5/8 divided by 5

First, we turn the 15 5/8 to a mixed number: 8 * 15 + 5 = 125/8

125/8 divided by 5/1 (which is equal to 5)

Next, we do Keep Change Flip.

Keep 125/8 the same, change the division to multiplication, and turn the 5/1 to 1/5.

1 * 125 = 125

8 * 5 = 40

Then, we get 125/40 = 3 5/40 BUT WAIT

We can reduce it once more! Divide 40 by 5

Each friend collected 3 1/8 bags of food.

What is the measure of AC?
ivolga24 [154]

Answer:

A. 88

Step-by-step explanation:

A circle is 360 degrees right ? so, 136 cant be right since 136 is almost half of a circle and that angle doesn't look nearly half, 44 and 22 cant be right either since AB is 44 degrees and its growing outwards so it cant be exactly 44 and it cant be less 44 (22)

so your answer will be A. 88

If f(5) = 12, f ' is continuous, and 7 f '(x) dx 5 = 16, what is the value of f(7)? f(7) =
olganol [36]

The value of function f(x) at x = 7 is f(7) = 28

For given question,

we have been given the value of function f(x) at x = 5.

f(5) = 12

We have been given that f'(x) is continuous on 5 and 7

Also, \int\limits^7_5 {f(x)} \, dx =16

We need to find the value of f(7)

Since ∀x, f'(x) = f'(x), f is a primitive function of f' .

And f ' is continuous

\Rightarrow \int\limits^7_5 {f(x)} \, dx =16\\\\\Rightarrow [f(x)]_5^7=16

⇒  [f(7) - f(5)] = 16

⇒ f(7) - 12 = 16

⇒ f(7) = 16 + 12

⇒ f(7) = 28

Therefore, the value of function f(x) at x = 7 is f(7) = 28
