Two lines intersect at a point. The vertical angles formed are supplementary.
Nastasia [14]

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

Here's a problem for the minds-good luck!
Art [367]

Answer:

20%

Step-by-step explanation:

  1. Set up a proportion: \frac{280}{1400} = \frac{x}{100}  
  2. Cross multiply, then divide: 280 × 100 = 28000, 28000 ÷ 1400 = 20
  3. So, 20% were satisfied with their car

I hope this helps!
