What is the value of x

X = 30°

Step-by-step explanation:

x = 105

Step-by-step explanation:

Skills needed: Triangle Angle Measures, Solving a One-Variable Equation

1) To get the answer, you need to know that all the angles inside a triangle add up to 180 degrees. This is very important in the future as well.

2) So to find x, we can make the equation: x + 30 + 45 = 180

3) You can combine like terms:

30 and 45 can be combined --> 30 + 45 = 75

4) Based on step 3, you can get: x + 75 = 180

Subtract 75 from both sides, and you will get: x = 105

Hope this helps and have a nice day! :] :) :D

step-by-step explanation:

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
