find the length of side X in simplest radical form with a rational denominator (giving brainliest and thanks to all!)
irina1246 [14]

Answer:

x= √10/2

Step-by-step explanation:

if you use trig. functions:

sin 45° = opposite side /hypothenuse = x/√5

sin 45° = √2/ 2

√2/2 = x/√5 multiply both sides by √5

x= (√2*√5)/2 = √10/2

if you use that is a 45-45-90 special triangle

the sides are x, and hypothenuse must be x√2 in this type of triangles so in our case:

x√2 = √5 divide both sides by √2

x= √5/√2 multiply by √2/√2 which =1 and help us get rid of the radical from the denominator

x= (√5*√2)/ (√2*√2) = √10/2

At what temperature would the centigrade and Kelvin scales give similar readings<br>​
Serjik [45]

Answer:

The formulas for converting between degree Celsius and degree Fahrenheit are:

°F = (°C * 9/5) + 32

°C = (°F - 32) * 5/9

To find the temperature when both are equal, we use an old algebra trick and just set ºF = ºC and solve one of the equations.

°C = (°C * 9/5) + 32

°C - (°C * 9/5) = 32

-4/5 * °C = 32

°C = -32 * 5/4

°C = -40

°F = (°F * 9/5) + 32

°F - (°F * 9/5) = 32

-4/5 * °F = 32

°F = -32 * 5/4

°F = -40

So the temperature when both the Celsius and Fahrenheit scales are the same is -40 degrees

Have a nice day!!!
