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

Given:

In triangle XYZ, x = 27 cm, y = 79 cm and .

To find:

The length of z.

Solution:

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

Putting the given values in the above formula, we get

Taking square root on both sides.

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

Therefore, the length of z is about 102 cm.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
