Two angles are vertical angles. one angle is labeled 2x. the other angle is labeled (x + 30). find the value of x

x = 30°

Step-by-step explanation:

Vertical angles are equal. Vertical angles are congruent angles. Vertical angles share the same vertices . They share the same corner points.

Since the two angles are vertical angle that means they are equal.

The first angle = 2x

the second angle = x + 30

To find the value of x

2x = x + 30

collect like terms

2x - x = 30

x = 30°

option 1

data plot with   3 dots over 33, 1 dot over 34, 2 dots over 35, no dot over 36, 1 dot over 37, 2 dots over 38, 4 dots over 39, and 2 dot over 40.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
