What is the length of the hypotenuse

Mathematics

Answer:

35 km

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2 + b^2 =c^2 where a and b are the legs and c is the hypotenuse

28^2 + 21^2 = c^2

784+441 = c^2

1225 = c^2

Take the square root of each side

sqrt(1225) = sqrt(c^2)

35 = c

Answer:

35 km

Step-by-step explanation:

The pythagorean theorem states that a^2+b^2=c^2. (The hypotenuse is c)

So, we will plug a and b in.

28^2+21^2=c^2

Then, simplify.

784+441=c^2

1225=c^2

c=35

Therefore, the hypotenuse is 35 km.

Someone help i'll give brainliest to right answer!
Bogdan [553]

Answer:

145

Step-by-step explanation:

angles in a pentagon add up to equal 540

Hence, 110 + 90 + 80 + 115 + v = 540

( note that we just created an equation that we can use to solve for v )

We now solve for v using the equation created

110 + 90 + 80 + 115 + v = 540

step 1 combine like terms

110 + 90 + 80 + 115 = 395

we now have 395 + v = 540

step 2 subtract 395 from each side

540 - 395 = 145

395 - 395 cancels out

we're left with v = 145

A dolphin can swim up to 40 miles per hour.what is the speed in feet per hour?
zalisa [80]
In this question, the speed of the dolphin is already given, but the unit is different. The speed of the dolphin is given as 40 miles per hour and it has to be converted to feet per hour.
We already know that 1 mile = 5280 feet
Then
40 mile = 5280 * 40 feet
            = 211200 feet
So the speed in feet per hour will be 211200 feet per hour. I hope the procedure is clear enough for you to understand. You can always use this method for solving similar problems without requiring any help from outside.
