D. Find the measure of angle x<br> Find the measure of angle x
Keith_Richards [23]

Answer:

x = 24 degrees

Step-by-step explanation:

You need to know, that one line has a total of 180 degrees. So, first solve for y by subtracting 180 - 103. You get 77. So y is 77 degrees. Now add 77 + 79 to get 156. Now subtract 180 - 156 to solve for x. You get 24 degrees.

Hope it helps!

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.
