Answer: DO you have a chart or something that i can actually help you with
Step-by-step explanation:
A line can be named either using two points on the line (for example, AB ) or simply by a letter, usually lowercase (for example, line m ).
The sum of interior angles of a triangle must add up to 180 degrees
if the triangle has an angle that is greater than 90 degrees, then it is considered obtuse
if the triangle has an angle that is 90 degrees, then it is considered right
if all angles are less than 90, then it is acute
find the missing angle "x"
180=60+80+x
is angle x less than, greater, or equal to 90 degrees?

It depends on what is being referred to by "this."
The description of the activity is that 10 drops are added twice and two readings are taken. If you do *that* 4 times, then a total of 20*4 = 80 drops will have been added.
If the activity referred to by "this" is the pair of acts {add 10 drops, read the volume}, then four repetitions will have added 10*4 = 40 drops.
Probably the expected interpretation is that "this" is {add 10 drops, read}, so 40 drops is likely the expected answer.
