Tan(x)+tan(y)=sin(x+y)/cos(x)cos(y)

Mathematics

tan(x) + tan(y) = \frac{sin(x + y)}{cos(x)cos(y)}
\frac{sin(x)}{cos(x)} + \frac{sin(y)}{cos(y)} = \frac{sin(x + y)}{cos(x)cos(y)}
\frac{sin(x)cos(y)}{cos(x)cos(y)} + \frac{sin(y)cos(x)}{cos(x)cos(y)} = \frac{sin(x + y)}{cos(x)cos(y)}
\frac{sin(x)cos(y) + sin(y)cos(x)}{cos(x)cos(y)} = \frac{sin(x + y)}{cos(x)cos(y)}
\frac{sin(x + y)}{cos(x)cos(y)} = \frac{sin(x + y)}{cos(x)cos(y)}

No. Mass is the measurement of how much matter is in something.
Take neutron stars for example; smaller than our sun but has more mass. Because of density.

PLEASE ANSWERRR NOW!!!
finlep [7]

The answer is [ yes; ΔJLK ~ ΔMLN by AA Similarity ]

AA similarity states that both triangles have corresponding angles that equal the same measure. Even though the question doesn't state the measure of the angles, the angles look the same.

ASA similarity states that two angles and a side equal the same in both triangles. Both triangles in the image aren't the same size, so, this is also false.

Best of Luck!

James bought a cake that weighs 3 and 1 over 4 pounds. How many ounces does the cake weigh? Show your work. (5 points)
kolezko [41]

The weight of James cake in ounces is 52 ounces and the Pint of water dispensed in 20 seconds is 24 pints

<h3>Weight</h3>

  • Weight of cake = 3 1/4 pounds

1 pound = 16 ounces

Number of ounces the cake weigh = 3 1/4 pounds × 16 ounces

= 13/4 × 16

= (208) / 4

= 52 ounces

  • Water dispensed per second = 0.15 gallons
  • Number of seconds = 20 seconds

1 gallon = 4 quarts

0.15 gallon = 0.6 quarts

1 quart = 2 pints

0.6 quart = 1.2 pints

Pint of water dispensed in 20 seconds = 1.2 × 20

= 24 pints of water
