A)360/6 = 60. 180-60 =120 degrees i think
b) 360/8 = 32.5. 180-32.5= 147.5 degrees i think

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

Can some one explain how to do this?

Delvig [45]

Answer:

see explanation

Step-by-step explanation:

Using the tangent and sine ratios in the right triangle EFG

tan60° = $\frac{opposite}{adjacent}$ = $\frac{FG}{EG}$ = $\frac{28}{EG}$ ( multiply both sides by EG )

EG × tan60° = 28 ( divide both sides by tan60° )

EG = $\frac{28}{tan60}$ ≈ 16.2 in ( to the nearest tenth )

--------------------------------------------------------------

sin60° = $\frac{opposite}{hypotenuse}$ = $\frac{FG}{EF}$ = $\frac{28}{EF}$ ( multiply both sides by EF )

EF × sin60° = 28 ( divide both sides by sin60° )

EF = $\frac{28}{sin60}$ ≈ 32.3 in ( to the nearest tenth )

Evaluate the expression for f = -6 and g = -1.<br> fg - f =

Arlecino [84]

Answer:

7

Step-by-step explanation:

Given the information from the question:

$fg - f = f \times g - f$

Next we can use the order of operations to find the value of the expression.

$fg - f = - 6 \times - 1 - ( - 1) \\ = 6 - ( - 1) \\ = 6 + 1 \\ = 7$

Can someone please help me answer this question asap thank you

Marianna [84]

Ross would be the correct answer. To figure it out you would divide 27/3 which is 9 and then 49/7 which is 7. So 9>7.

Leonard is studying the relationship between the fuel efficiency in miles per gallon (mpg), y, and the speed in miles per hour (

Nataliya [291]

Answer:

D. There is a nonlinear relationship between the speed and fuel efficiency.

Step-by-step explanation:

A desirable residual plot should show a horizontal band with points randomly distributed about the horizontal axis.

Leonard's plot is definitely nonlinear.

The residuals show a good fit to a parabola.

This suggests that the relation between speed and fuel efficiency may be parabolic.
