These two lines create vertical angles, which are congruent. That means angle z = 60 degrees. Since angle z and the angle represented by the expression 6x + 60 are supplementary (they are adjacent angles that add to equal 180 degrees), you can set up the following equation to find x:
6x + 60 + 60 = 180
6x + 120 = 180
6x = 60
x = 10
Answers:
x = 10
z = 60
68 minus 19 is 49
So the answer is there are 49 more children in the school then on the playground.
Answer:
x=133
Step-by-step explanation:
the missing angle plus are supplementary. the missing angle is 47 as a triangle must be 180 degrees.
therefore 180=x+47
