What is the value for X?​
Luda [366]

Answer:

5

Step-by-step explanation:

6x + 4 + 73 + 73 = 180

6x + 150 = 180

6x = 30

x = 5

Those little marks on AB and BC denote congruence. That makes the triangle isoceles. That means the base angles are equal. Both 73.

Triangle Sum Theory states all angles of a triangle add to 180.

Answer: 3 * n = 15

5 students tried out for the baseball team.

Step-by-step explanation:

n is the amount of kids who tried to try out for the baseball team.

15 kids tried out for the hockey team, and that’s 3 times as many as the amount who tried out for the baseball team, so 3 times n = 15, or 3 * 5 =15

hope this helped!
