Answer:

Cos of an angle by definition of its ratio is side adjacent/hypotenuse.  The side adjacent to angle Z cannot be the hypotenuse, so it has to be 10. he hypotenuse is 26.  Therefore, cosZ= 10/26 = 5/13

Find an equation of a line with the x- and y-intercepts below. Use exact fractions when necessary.
Ludmilka [50]

Answer:

The line with the x- and y-intercepts below has the following equation:

f(x) = \frac{5x}{7} - 5

Step-by-step explanation:

The equation of the line has the following format:

f(x) = ax + b

We are given two points, we are going to substitute them into the above equation, and find the equation of the line given the conditions.

Solution

Starting from the y-intercept makes the solution easier, since the term a is multiplied by 0

y-intercept -5

This means that when x = 0, y = f(x) = -5, so:

f(x) = ax + b

-5 = a(0) + b

b = -5

For now, the line has the following equation:

f(x) = ax - 5

x-intercept 7

This means that when y = f(x) = 0,x = 7, so:

f(x) = ax - 5

0 = 7(a) - 5

7a = 5

a = \frac{5}{7}

So, the line with the x- and y-intercepts below has the following equation:

f(x) = \frac{5x}{7} - 5
