Answer:
x = 60°
Step-by-step explanation:
we know that triangles have 180 degrees so we can set up an equation:
86 + 34 + x = 180
now we subtract the sum of 86 and 34 from both sides to get a final answer:
x = 60
so lets plug our x value into the previous equation to check our answer:
86 + 34 + 60 = 180
when we add these numbers together, the equation checks out so we know our answer is correct.
hope this helps!
