If two angles are equal and supplementary, the angles are A. acute angles B. right angles C. acute angles

right angles.B

Step-by-step explanation:

let x and ybe angles.

x+y=180

also x=y

x+x=180

2x=180

x=180/2=90

y=x=90

right angles

Step-by-step explanation:

Let x be the angle

X is also the other angle since they are equal

Supplementary means they add to 180

x+x = 180

2x = 180

Divide by 2

2x/2 = 180/2

x= 90

They are right angles

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set
