Answer:
x=60
Step-by-step explanation:
The three angles of a triangle add to 180 degrees
40+80+x = 180
Combine like terms
120+x =180
Subtract 120 from each side
120-120+x = 180-120
x = 60

If m<8 is 70 degrees, then <7 is (180-70), or 110, degrees.
Angles 3 and 7 are the same because lines m and n are parallel.
Thus, <3 = <7 = 110 deg.
45/75 = 9/15 = 3/5
you would first divide both the numerator and the denominator by 5 and the by 3.
