Answer 1

Answer: So A i guess how big they are? So n-1*90 means 10*180=1800. B 1800/12=150. C no, the max size the angles can have are 120 degrees (? Not sure about this)

The vertices of a triangle are P(-8, 1), ((-6, 8), and R(4, -3). Name the vertices of the imagereflected across the x-axis.

Answers

The vertices of the image reflected across the x-axis are P'(-8,-1), Q'(-6,-8), and R'(4,3).

What is a vertices?

A point on a polygon where the sides or edges of the object meet or where two rays or line segments meet are called vertices.

The given vertices are P(-8, 1), Q(-6, 8), and R(4, -3).

To reflect the points across the x-axis, the x variable would stay the same while the y variable becomes the opposite.

So, the given vertices changed like:

P(-8,1) will become P'(-8,-1)

Q(-6,8)will become Q'(-6,-8)

R(4,-3) will become R'(4,3)

Hence, we can say that P'(-8,-1), Q'(-6,-8), and R'(4,3) are the vertices of the image reflected across the x-axis.

Answer:

P'(-8,-1)

?'(-6,-8)

R'(4,3)

Step-by-step explanation:

If you were to reflect the points across the x-axis, then the rule here would be that the x variable would stay the same while the y variable becomes the opposite.

So,

P(-8,1) = P'(-8,-1)

?(-6,8) = ?'(-6,-8)

R(4,-3) = R'(4,3)

Need help! Express 86% as a fraction in its lowest form. Do the same with 80%,59% and 98%

Answers

percent means parts out of 100
x%=x/100

so

86%=86/100=43/50

80%=80/100=8/10=4/5
59%=59/100
98%=98/100=49/50

86% = 43/50
80% = 4/5
59% = 59/100
98% = 49/50
