Answer:

The are 125:9

Step-by-step explanation:

When we know the scale factor

The lengths are related by the scale factor

The areas are related by the scale factor squared

The volumes are related by the scale factor cubed

Since the scale factor is 5:3

Cube each side

5^3: 3^3

125:9

The are 125:9

Find x<br> A. 22√2<br> B. 22<br> C. 11√3/3<br> D. 11√3
mel-nik [20]

Answer

22\sqrt{2}

Step-by-step explanation:

First we gave a name to the side that is common for both triangles, can be Y for example.

Using trigonometric functions we can make a relationship between the two angles that we have and the magnitud of the side.

sin(45)=\frac{11}{Y}  \\ , Because sin(x)= op/hip

cos(60)=\frac{Y}{x} , Because con(x)=ad/hip

Having this equations, we can solve the system and find x

Y=\frac{11}{sin(45)} \\Y=cos(60)*x

we equal Y and solve

\frac{11}{sin(45)}=cos(60)*x\\ x=\frac{11}{sin(45)*cos(60)} \\x=\frac{11}{\frac{\sqrt{2} }{2} *\frac{1}{2} } \\x=\frac{11}{\frac{\sqrt{2} }{4} } \\x=\frac{44}{\sqrt{2} }\\

Then we rationalize

x=22\sqrt{2}

Leya [2.2K]

Answer:

Step-by-step explanation:

a. sin^-1(sin theta) = theta

   (1/sin)(sin theta) = theta

<em>the sines cross out</em> theta = theta

b. cos(cos^-1x) = x

   cos(x/cos) = x

<em>the cosines cross out </em>x = x
