Answer:
60
Explanation:
if the bottom corner on the left is a right angle, its 90. because we already have 30. its 90+30+120. Triangles total angles is 180.
n=60
The sum of interior angles in a triangle will always be equal to 180. Knowing this, we can set up the following equation:
n+90+30=180
n+120=180
Subtract both sides by 120
n+120-120=180-120
I hope this helps!
