94 rounded to the nearest tenth would either be 90 if you go back or 94 if you just stay that way. As long as the number doesn't go up.

Answer:
The angles are 36° and 144°
Step-by-step explanation:
Let
x-----> one of the angles formed by two intersecting lines
y----> the other angle formed by two intersecting lines
we know that
x+y=180° -----> Equation A (by supplementary angles)
x=4y -----> equation B
substitute equation B in equation A
4y+y=180°
5y=180°
y=36°
Find the value of x
x=4(36°)=144°
therefore
The angles are 36° and 144°
