Hey there!!
When you divide fraction you change the sign to multiplication and you have to reverse the 2nd fraction which is called reciprocal
1/2* 3/1(Not 1/3 because you reverse it)
1/2*3/1=3/2
3/2= 1 1/2
So your final answer is 1 1/2
Hope this helps!

The sum of the interior angles of all triangles is 180 degrees. This means you can set all the angles' expressions equal to 180 and solve algebraically for x.
180 = 3x + 2x + x
180 = 6x
30 = x
Answer:
30°
