Answer:

Below.

Step-by-step explanation:

7) c^2 = a^2 + b^2

15^2 = 11^2 + b^2

b^2 = 225 - 121 = 104

b = √104

= √4√26

= 2√26.m

8). 4^2 = a^2 + (√6)^2

a^2 = 16 - 6

a^2 = 10

a = √10.

The diagram shows two parallel lines and transversal. If the measure of <6 is 140, what is the measure of <1?

alexandr402 [8]

Angles 6 and 3 are supplementary. If angle 6 is 140, then angle 3 is 40. Because those lines are parallel and cut by a transversal, then angles 3 and 1 are corresponding and congruent. That means that angle 1 measures 40° also. Choice D.

The given table values represents a liner equation. What is the slope?

Arada [10]

Answer:

A. 2

Step-by-step explanation:

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1}$

Use any two points given in the table of values. Let's use (1, 5), (3, 9)

Let,

$(1, 5) = (x_1, y_1)$

$(3, 9) = (x_2, y_2)$

Plug these values into the slope formula:

$slope (m) = \frac{9 - 5}{3 - 1}$

$slope (m) = \frac{4}{2}$

$slope (m) = 2$
