What is the angle measure of angle ABC?​
Aliun [14]

Answer:

92°

Step-by-step explanation:

First, find the value of x.

3x + 23 = 4x (corresponding angles are congruent)

Subtract 3x from each side

23 = 4x - 3x

23 = x

x = 23

Angle ABC = 4x

Plug in the value of x

Angle ABC = 4(23)

Angle ABC = 92°

In a lottery, a 4 digit number from 0000 to 9999 is randomly selected. Find the probability that the number selected begins with
Bingel [31]

Since the choices is from 0000 to 9999, therefore there are a total of 10,000 possibilities.

 

The possibilities that the number begins with a 3 and ends in a 2 or 0 is:

possibilities = 1 * 10 * 10 * 1 + 1 * 10 * 10 * 1 = 200

 

Therefore the probability is:

P = 200 / 10,000 = 0.02 = 2%

 

<span>So there is a 2% probability.</span>
