Answer:
use the fact that triangles only have room for 180 degrees inside, so all the angles must add up to 180, no more, no less. You can also jsut insert the options for x values until you find the right one(shouldnt take too long).

A multiple is a number that can be divided by that number with no remainder. For example, multiples of 5 are 5, 10, 15, and 20.
A multiple of 12 is basically 12 × (number of multiple), for example, if you want the second multiple of 12, you would multiply 2 by 12.
So multiply 12 by 1, 2, 3, 4, and 5.
12×1=12
12×2=24
12×3=36
12×4=48
12×5=60
The first five multiples of 12 are 12, 24, 36, 48, and 60.

Answer:</h2><h2>The theoretical probability of four students from your school being selected as contestants out of 8 possible contestants spots =
</h2>
Step-by-step explanation:
The number of students participated = 30
Total audience = 150
By probability , to find the solution = 
where n(E) is the number of favorable outcomes,
n(S) is the number of total outcomes.
n(S) is the number of ways any 8 students can by picked from the audience= 
n(E) is the probability of picking four students from our school and five students from another school.
n(E) = 
= 
=
