Respuesta :

X=4
This adds up to a straight line (180)
Subtract 180-140 = 40
Now divide 40/10
You get 4

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
