Answer:
See explanation
Step-by-step explanation:
Consider triangles ACM and BCM. In these triangles,
- given;
- definition of perpendicular lines CM and AB;
- reflexive property.
So,
by ASA postulate (if one side and two angles adjacent to this side of one triangle are congruent to one side and two angles adjacent to this side of another triangle, then two triangles are congruent).
Two-column proof:

That is the correct answer
2/5 = x/30......2 in to 5 sec = x in to 30 sec
cross multiply
5x = 60
x = 60/5
x = 12 inches <==
