Triangle XYZ, X equals 27 cm, Y equals 79 cm and angle C equals 142Degrees. Find the length of Z, to the nearest centimeter.

Oksi-84 [34.3K]

Given:

In triangle XYZ, x = 27 cm, y = 79 cm and $\angle C=142^\circ$ .

To find:

The length of z.

Solution:

In triangle XYZ, using the Law of cosine, we get

$z^2=x^2+y^2-2xy\cos Z$

Putting the given values in the above formula, we get

$z^2=(27)^2+(79)^2-2(27)(79)\cos (142^\circ)$

$z^2=729+6241-4266(-0.788)$

$z^2=6970+3361.608$

$z^2=10331.608$

Taking square root on both sides.

$z=\pm \sqrt{10331.608}$

$z=\pm 101.6445178$

Approx the above value to the nearest number and side length cannot be negative. So,

$z\approx \pm 102\text{ cm}$

Therefore, the length of z is about 102 cm.

If y = 3 when x = 2. find x when y = 5.

ahrayia [7]

Y = 3 x = 2
if y = 1 x = ?

x = 3/2
x = 1.5
x = 5*1.5 ( y = 5 x = ?)
x = 7.5
(IF THE ANSWER IS WRONG)
may be this can be that answer

x = 2/3
x = 0.67
x = 0.67*5
x = 3.35

check the answer either first or second method is correct

What is the volume of the cylinder

Harman [31]

The volume of a cylinder is given by

$V = A_b\cdot h$

where $A_b$ is the base area, and $h$ is the height.

We are already given the height, which is 10.

We can deduce the base area since we are given a diameter: the radius is half the diameter, so it's 8, and the area of a circle is given by

$A_b = \pi r^2 = \pi 8^2 = 64\pi$

So, the volume is

$V = A_b\cdot h = 64\pi \cdot 10 = 640\pi \approx 2010.6193\ldots$
