Answer:

53 Meters.

Step-by-step explanation:

34*34 + 41*41 = 2837.

1156 + 1681 = 2837.

The square root of 2837 would be your answer.

34*34 + 41*41 = 53.26349 * 53.26349

a*a + b*b = c*c.

a² + b² = c².

Answer:

21.74

Step-by-step explanation:

AC^2 = AB^2 + BC^2

AC^2 = 34^2  +  41^2

AC^2 =  1156 + 1681

AC^2 = 2837

AC     = Square root of 2837

AC     =  53.26..

meters saved by walking through the pond = (AB+BC)-53.26

=>  (34+41)-53.26

=>   75 - 53.26

=>    21.74

hope this helps:)

Find the area of rectangle PLUM
torisob [31]

Answer:

A = 53.34 units ^ 2

Step-by-step explanation:

To find the length of the rectangle we solve the PLA triangle

Using the Pythagorean theorem we find the PL side.

PL = \sqrt{4^2+12^2}\\PL = \sqrt{16+144}\\PL = 12.65

Then the length of the rectangle is 12.65

Now we solve the MALU triangle. Where MU = PL

We use the Pythagorean theorem:

MU^2+LU^2 = (MA + AL)^2\\12.65^2+LU^2 = (MA+12)^2

Where LU and MA are unknown.

Finally we solve the triangle MPA

MA^2 + PA^2 = PM ^2

Where PM = LU

So:

MA^2 + 4^2 = LU^2

Now we have two equations and two unknowns. So we solve the system.12.65^2 + LU^2 = (MA + 12) ^2  (i)

MA^2+4^2 = LU^2  (ii)

We introduce (ii) in (i)

12.65^2 + MA^2+16=MA^2+24MA+144

Now we clear MA

160.02+16-1 44 = 24MA

32.02 = 24MA

MA = \frac{32.02}{24}

MA = 1.3342 (iii)

Now we introduce (iii) in (ii)

1.3342^2 + 4^2 = LU^2

LU = 4.2166

Now we have the length of the rectangle and also its width.

The area A of a rectangle is:

A = l*w

Where

 l = length

w = width

A = 4.2166*12.65

A = 53.34 units^2

I need help .. so can somebody help me please ? what two number and get 10 and -24 ?
Trava [24]
What 2 numbers do you multiply to get 10? In other words, what number can you multiply with another number to get 10? 

The formula to solve this would be:

X x Y = 10

There are at least two combinations of two numbers that you can multiply together to get 10.

For your convenience, we have made a list of all the combinations of two numbers multiplied by each other that will make 10:

<span>1 x 10 = 10
2 x 5 = 10
5 x 2 = 10
10 x 1 = 10
