Complementary is which add up to 90 °
8)
59+31=90° complementary angles.
supplementary is which add up to 180°
10) 156+24=18 supplementary angles
12)
shows right angle=3x+45=90
3x=45
x=15°

14) supplementary angles
2x+3x+25=180
5x+25=180
x=31°

16) again it makes supplementary angles
x+2x+21=180
3x+21=180
x+7=60
x=53°

I hope this information helps!

Remember that a straight line has an angle measure of 180.

Two angles whose sum equals 180 are supplementary angles.

Two angles whose sum equals 90 are complementary angles.

Calculate the midpoint between (2,-5) and (4, -7).
balandron [24]

The midpoint between (2,-5) and (4, -7)  is Option D.(3-6)

Step-by-step explanation:

Given:

Points (2,-5) and (4, -7)

To Find:

Midpoint of the points=?

Solution:

The midpoint that lies between the two points is given by

(x_m, y_m) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})

Where

(x_m, y_m)= coordinates of the midpoint

(x_1, y_1)= coordinates of the first point

(x_2, y_2)= coordinates of the second point

we have,

x_1= 2

y_1= -5

x_2= 4

y_2= -5

Substituting the values in the mid point formula,

(x,y)=(\frac{(2+4)}{2},\frac{(-5-7)}{2})

(x,y)=(\frac{(6)}{2},\frac{(-12)}{2})

(x,y)=(3,-6)
