Two lines intersect at a point. The vertical angles formed are supplementary.

Mathematics
1 answer:
Nastasia [14]3 years ago
8 0

we know that

<u>Vertical angles</u> are a pair of opposite and congruent angles formed by intersecting lines.

so

Let

x1---------> angle vertical 1

x2---------> angle vertical 2

x1=x2 ------> equation 1

in this problem

if the vertical angles formed are supplementary

that means that

x1+x2=180 ------> equation 2

substitute equation 1 in equation 2

x1+x1=180

2x1=180

x1=180/2

x1=90 degrees

therefore

<u>the answer is</u>

The vertical angles are right angles

A scale for a drawing is 5 centimeters= 1 meter. What is the scale in terms of centimeter to centimeters
umka2103 [35]

The scale in cm to cm is:

1 cm = 20 cm

Step-by-step explanation:

Scales are used to draw maps and blueprints of large objects on paper.

Given scale is:

5 centimeters = 1 meter

WE have to find the centimeter to centimeter scale. In order to do so, we have to convert the meters into centimeters

As there are 100 centimeters in a meter

So,

the scale will be:

5 cm = 100 cm

Simplifying:

The scale in cm to cm is:

1 cm = 20 cm

Y=1/2x+3<br> -x+27=-6 <br><br> solve using substitution
Nat2105 [25]

Answer:

y= 19.5    x=33

Step-by-step explanation:

-x + 27= -6

(subtract 27 on both sides)

-x= -33

(divide by negative 1 on both sides)

x= 33

(substitute x into the first equation)

y= 1/2x + 3

y= 1/2(33) +3

y= 16.5 +3

y= 19.5

hope this helps :))
