Answer:
12
Step-by-step explanation:
28 - 10 = 18 divided by 1.50 = 12
Answer: To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
Step-by-step explanation:
let's firstly convert the mixed fractions to improper fractions and then add.

Answer:
the answer is 2..............
Answer:
The answer is D.
Step-by-step explanation:
It is D because they cannot be negative feet away and if the fisherman is 12ft above water and the diver is 40ft below than 40 + 12 = 52. Hope this helps.
