If angle ABC is 90°, then angle CBD is 90°:

Angle ABD=90°
3x°=90°
3x=90
Solving for x:
3x/3=90/3
x=30

Angle CBD=90°
(2x+3y)°=90°
2x+3y=90
x=30
2(30)+3y=90
60+3y=90
Solving for y:
60+3y-60=90-60
3y=30
3y/3=30/3
y=10

Answer: Option a. 10

The type of match to use in a Vlookup() function to assess the resort fee as a possible additional cost for a particular room is
schepotkina [342]

Answer:

An approximate match

Step-by-step explanation:

The vlookup (vertical lookup) function is a search function in excel used in locating values in an excel table.

The vlookup syntax is written as:

=VLOOKUP(value, table, col_index, [range_lookup])

The range_lookup is an optional parameter which is used to indicate if the search should be for an exact match or approximate match. Since a column, resort fee will be used as a possible additional cost; the search would be required to return an approximate search rather than an exact match in other for the search condition to be adequately implemented.
