Hey do you need to show your work for these? I found an answer key

Step-by-step explanation:

We need to use law of cosines

c²=a²+b²-2abcos(C)

let x= angle xzy

plugging in what we have the equation looks like

17²=22²+20²-2*22*20*cos(x)

289=484+400-880cos(x)

.676136364=cos(x)

x=47.45754235

b.)

The smallest angle should be opposite to the smallest side

Using the law of cosines again we get

9²=13²+17²-2*13*17*cos(x)

81=458-442cos(x)

.852941176=cos(x)

x=31.46697634

Solve for x . Help me solve them

Tresset [83]

$\\(1).\\\\(1.7898)^{2x} = (1.7898)^6\\\\\implies \ln(1.7898)^{2x} = \ln(1.7898)^6\\\\\implies 2x \ln(1.7898) = 6 \ln(1.7898)\\\\\implies 2x =6\\\\\implies x = \dfrac 62 =3\\\\(3).\\\\2^{5x -6} = 4^{x+9}\\\\\implies 2^{5x -6} = (2^2)^{x+9}\\\\\implies 2^{5x-6} = 2^{2x+18}\\\\\implies \ln(2^{5x-6}) = \ln(2^{2x+18})\\\\\implies (5x -6) \ln 2 = (2x +18) \ln 2\\\\\implies 5x -6 = 2x +18\\\\\implies 5x -2x = 18 +6\\\\\implies 3x = 24\\\\\implies x = \dfrac{24}3 =8$

Find the diagonal of the rectangular prism to the nearest tenth.<br> 4 in<br> 3 in<br> 10 in

hoa [83]

Given:

Consider the dimensions of a rectangular prism are 4 in by 3 in by 10 in.

To find:

The length of the diagonal.

Solution:

Length of diagonal of a rectangular prism is:

$d=\sqrt{l^2+b^2+h^2}$

Where l is length, b is breadth and h is height.

The dimensions of a rectangular prism are 4 in by 3 in by 10 in. So, the length of diagonal of the rectangular prism is:

$d=\sqrt{(4)^2+(3)^2+(10)^2}$

$d=\sqrt{16+9+100}$

$d=\sqrt{125}$

$d=5\sqrt{5}$

Approximate the value to the nearest tenth.

$d\approx 11.2$

Therefore, the length of diagonal of the rectangular prism is 11.2 in.
