Answer:

11.66

Step-by-step explanation:

As far as I remember the Pythagorean theorem states that A squared + B squared = C Squared.   A and B are your 2 input numbers so therefor 6squared + 10squared =136 but you have to find the Square root of that because you added the other two squared numbers. Your answer is approximately 11.661903

The sum of two numbers is 52 . The larger number is 2 less than twice the smaller number .What are the numbers

Answers

Answer:

35.34 and 16.66

Step-by-step explanation:

Given data

let the numbers be x and y

the smaller number = x

the larger number = y

x+y=52--------1

The larger number is 2 less than twice the smaller number

y=2x-2-------2

put y= 2x-2 in eqn 1

x+2x-2=52

3x-2=52

3x=52-2

3x=50

x= 50/3

x= 16.66

put x=16.66 in eqn 1 to find y

x+y=52

16.66+y= 52

y=52-16.66

y= 35.34

Hence the numbers are

35.34 and 16.66

Check

35.34+16.66= 52

Answer:

surface area =0.1357

Step-by-step explanation:

first, find the triangle area

to find use triangle area= base x height divided by 2

so .18 x .23

=0.0414

divided by 2

= .0207

multiplty 0.0414 by 4 because theres a total of 4 triangle sides

.0207 x 4 = 0.0828

now find the area of the square on the bottom

area= base x height

.23 x .23 = 0.0529

now add the two areas together

0.0529 + 0.0828= 0.1357

Hi!

This involves applying trigonometry.

Because we are trying to figure out the height of Burj Khalifa, we are trying to find the length of AB. We already have CB, which is the adjacent side with respect to the angle. Then, AB would be the opposite side with respect to the angle given.

Remember SOH CAH TOA? Well, we have the adjacent and opposite sides involved in this, so we use the tangent function!

It will be as follows:

tan(73) = AB / 250

AB = (250)(tan(73))

AB = 817.71 meters
