ANSWER:

[8] By intersecting secant theorem,

x + 27 = 9 + 21
x + 27 = 30
x = 30 – 27
x = 3

[9] By intersecting secant theorem,

7x + 2 + 18 = 6x + 3 + 20
7x + 20 = 6x + 23
7x – 6x = 23 – 20
x = 3

[10] By secant property,

x + 7 = 13 + 8
x + 7 = 21
x = 21 – 7
x = 14

Answer:

The answer to your question is letter A (2/3)

Step-by-step explanation:

Formula

tangent Ф = $\frac{opposite side}{adjacent side}$

For A

opposite side = 2

adjacent side = 3

Substitution

tan Ф = $\frac{2}{3}$

Result

tan Ф = $\frac{2}{3}$

What is the length of segment CD question mark

blagie [28]

Answer:

CD = two square root of 10 end square root

Step-by-step explanation:

To find the length of a segment, use the distance formula. Substitute the order pairs for the endpoints of the segment. CD has the end points (-7, -4) and (-1, -2).

$d = \sqrt{(y_2-y_1)^2 + (x_2-x_1)^2} \\\\d = \sqrt{(-4--2)^2 + (-7--1)^2} \\\\d = \sqrt{-2^2 + -6^2}\\\\d = \sqrt{4 + 36}\\\\d=\sqrt {40} = 2\sqrt{10}$

Solve for x please, explantion is not nesscary but it would help me

Ber [7]

Answer:

x = 100 degrees

Step-by-step explanation:

There are 360 degrees total in this figure. Since 160 is already shown, we can subtract it from 360 to solve for x. 360 - 160 = 200. So, 200 degrees is split among the remaining values, which are 2 x's. Since each x has the same value, we can divide 200 evenly among the two of them. 200/2 = 100. So, x = 100.

P.S.: Sorry if this is long-winded, I haven't taken geometry in a while. I hope I explained it well enough for you and other Brainly users.
