Answer:
A. 4
Step-by-step explanation:
140 + 40 = 180 since that whole angle adds up to 180 which is a straight angle
which means the angle isn't gay which is a good angle LOL
the angle that 10 is in is an acute angle
acute angles are below 90 degrees
so 4 x 10 is 40 which is below 90
so since it is the only thing below 90
Its the answer
