Find the value of z, secant and tangent angles
NeTakaya

Answer:

z = 110

Step-by-step explanation:

The measure of an angle created by the intersection of two secants outside a circle is half the difference of the angles it intercepts. In this it would be:

2x + 15 = 1/2 * (10x + 20 - 80)

We can now solve:

4x + 30 = 10x - 60

30 = 6x - 60

6x = 90

x = 15

This means the values of 10x + 20 is 10(15) + 20, which is 170.

Now, we can add up all the arcs in a circle, which sum to 360 degrees:

360 = z + 170 + 80

360 = z + 250

z = 110

How do I do this? Please explain it. Thank you.
Westkost [7]

Answer:

slope = - \frac{14}{3}

Step-by-step explanation:

the slope of the secant line in the closed interval [a, b ] is

slope = \frac{f(b)-f(a)}{b-a}

here [a, b ] = [1, 4 ]

f(b) = f(4) = - 2^{4} + 5 = - 16 + 5 = - 11

f(a) = f(1) = - 2^{1} + 5 = - 2 + 5 = 3

slope = \frac{-11-3}{4-1} = \frac{-14}{3} = - \frac{14}{3}
