Answer:
71
93.5
x=15.5
Step-by-step explanation:
(2x+40)+(5x+16)+(x)=180
you have to put all the measures together and equal it to 180. when it comes to triangles, all the angles added together are equal to 180.
now solve the equation and you should get this:
x=15.5
the next step is to solve the give equations separately:
2(15.5)+40=71
5(15.5)+16=93.5
(15.5)=15.5
now to check the work, you have to add all the measures that were just calculated:
71+93.5+15.5=180 so check!
