Answer:
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
