Do you recognize that the hypotenuse here has the length 22 and that the opposite side is the unknown (x)?  The angle is 21 degrees.

This is a perfect application of the tangent function:

tan 21 deg = opp / adj = opp / 22 = x / 22

tan 21 deg = 0.384                             so x would be 22 tan 21 deg, or
                                                                x = 22*(0.384)
                                                                   = 8.45  (answer)

Answer:

(x + 5) B. (x - 5) C. (x + 3) D. (x - 3) = = 0

Step-by-step explanation:

The calculator performs basic and advanced operations with fractions, expressions with fractions combined with integers, decimals, and mixed numbers. It also shows detailed step-by-step information about the fraction calculation procedure. Solve problems with two, three, or more fractions and numbers in one expression.

Rules for expressions with fractions:

Fractions - use the slash “/” between the numerator and denominator, i.e., for five-hundredths, enter 5/100. If you are using mixed numbers, be sure to leave a single space between the whole and fraction part.

The slash separates the numerator (number above a fraction line) and denominator (number below).

Mixed numerals (mixed fractions or mixed numbers) write as non-zero integer separated by one space and fraction i.e., 1 2/3 (having the same sign). An example of a negative mixed fraction: -5 1/2.

Because slash is both signs for fraction line and division, we recommended use colon (:) as the operator of division fractions i.e., 1/2 : 3.

Decimals (decimal numbers) enter with a decimal point . and they are automatically converted to fractions - i.e. 1.45.

The colon : and slash / is the symbol of division. Can be used to divide mixed numbers 1 2/3 : 4 3/8 or can be used for write complex fractions i.e. 1/2 : 1/3.

An asterisk * or × is the symbol for multiplication.

Plus + is addition, minus sign - is subtraction and ()[] is mathematical parentheses.

The exponentiation/power symbol is ^ - for example: (7/8-4/5)^2 = (7/8-4/5)2

Mr.bonds math class starts at 11:30 if the class ends at 1:00 how long is his teaching.
Irina-Kira [14]
11:30 and 1:00
assuming that it is
11:30 AM to 1:00 PM and not 11:30 AM to 1:00 AM

11:30 to 1:00 cannot be directly counted
the hours go like  this
1,2,3,4,5,6,7,8,9,10,11,12=AM
then after 12AM then
1,2,3,4,5,6,7,8,9,10,11,2=PM

60 minutes in 1 hour so
11:30=11 hours and 30 mins
how far to 12 AM?
12 AM=12 hours=11 hours and 60 minutes
11 hours and 60 minutes-(11 hours and 30 mins)=30 minutes

then from 12 AM to 1 PM=1 hour so
time total difference is 1 hour and 30 minutes
