Answer:

Scientists can tell by observing the seismic waves that are recorded all over the surface of the earth from distant earthquakes. The seismic waves are reflected (bounced off) layers of different density, and they are refracted (bent) when they enter layers of different density.

The area of a rectangle is 45 cm2. Two squares are constructed such that two adjacent sides of the rectangle are each also the s

lorasvet [3.4K]

Answer:

The length of sides of one square is 5cm and length of sides of another square is 9cm

Step-by-step explanation:

Let the length of rectangle be x and width of rectangle be y.

We have given,

Area of rectangle = 45 cm²

i.e. Area of rectangle = x·y = 45 or xy = 45 ---------(1)

Next, two squares are constructed from two adjacent sides of rectangle.

i.e Side length of one square will be x and side length of another square will be y.

Area of one square = x²

And area of another square = y²

According to problem,

Sum of area of two squares is 106 cm²

∴ x²+y² = 106 ---------------(2)

From equation (1) and (2) , we can find x and y.

xy = 45 or x = $\frac{45}{y}$ , Plug this in equation (2).

We get,

x² + y² = 106

or $(\frac{45}{y} )^{2} + y^{2} =106$

or $\frac{45^{2} +y^{4} }{y^{2} } =106$

or $45^{2} + y^{4} = 106y^{2}$

On solving this equation we get ,

y²=81 or 25

or y = 9 or 5

for y =9 , x= $\frac{45}{9} =5$

or for y = 5 , x = $\frac{45}{5} =9$

Hence the length of sides of one square is 5cm and length of sides of another square is 9cm

Calculate the value of 0. Write your equation.

Crazy boy [7]

Answer:

θ = 67.4°

Step-by-step explanation:

using the <u>SOHCAHTOA </u>method,

Here opposite is 12 cm, hypotenuse is 13 cm, adjacent is 5 cm.

Using the formula:

$sin(\beta ) = \frac{oppsoite }{hypotenuse}$

$sin(\beta ) = \frac{12}{13}$

$\beta = sin^{-1}(\frac{12}{13} )$

β = 67.4°
