Answer:

Step-by-step explanation:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

34kurt

Answer: She will have $700 left over.

Step-by-step explanation: Since we know that a rectangle has two sides with the measurement, we can add the sides. 37+37+25+25=124. The fencing in 124 feet in total. Multiply the 124 feet by the price per foot. 124 x 75 =9,300. Subtract the price from your total amount of money. 10,000 - 9,300 = $700. She will have $700 left over.

Find the exact value of tan 195 degrees
melamori03 [73]

Answer:

tan(195\°)=tan(15\°)=0.267949192431123...

Step-by-step explanation:

We know that

tan(195\°)=tan(15\°), because 195\° - 180\° = 15\°.

Now, angle 15° or 195° is not an important angle which can be solve by a given table like 30°, 45° or 60°. This means we have to use the calculator to find the more exact value, which is

tan(195\°)=tan(15\°)=0.267949192431123...
