Pythagorean theorem! i slacked off very the weekend trying to sleep cause i've been overworked

20

Step-by-step explanation:

The Pythagorean Theorem says if you have a right triangle with legs then:

.

You are given leg measurements 12 and 16.

You are given the hypotenuse measurement but are asked to find it.

Take square root of both sides:

the Pythagorean theorem states that the square of two sides of a right triangle other than the hypotenuse is equal to the square of the hypotenuse

Step-by-step explanation:

therefore, by using the above Pythagorean theorem,

12² + 16² = x²

=> 144 + 256 = x²

=> 400 = x²

=> √400 = x

=> 20.

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours

i think it will be 4feet long of what i comprehend
