Answer:
x is 33
Step-by-step explanation:
All 3 of these angles added together create a straight line, and such lines always measure 180°, so if we create an equation with the 3 angles being added together, set it equal to 180, and solve, we'll find the answer:
104+x+(x+10)=180
104+x+x+10=180 (use the distributive property to remove parenthesis)
104+10+x+x=180 (rearrange terms)
114+2x=180 (combine like terms)
2x=180-114 (subtract 114 from both sides)
2x=66
x=33 (divide 2 from both sides)
