If < A and < B are vertical angles, and < A = 2x - 11 degrees, and < B = x + 7 degrees, find x.

Tema [17]

Answer:

x=18

Step-by-step explanation:

Vertical angles are congruent. This means that they are equal to each other. So, to solve set them equal to each other and isolate x. First, set up the equation. Then, subtract x from both sides. Finally, add 11 to both sides and simplify.

1) $2x-11=x+7$

2) $x-11=7$

3) $x=18$

A positive angle less than 360 degrees that is coterminal with -5 degrees is

nadya68 [22]

Answer:

$\theta = 355$

Step-by-step explanation:

Given

Let the angle be $\theta$

$\theta < 360$

$\theta$ is co-terminal with -5

Required

Find $\theta$

Start by dividing 5 by 360 (ignore the negative)

$\frac{5}{360} = 0.0138$

The nearest integer greater than 0.0138 is 1.

<em>This implies that if you were to draw for this problem, the circle you would draw to show -5 degrees would go around 1 time</em>

So, $\theta$ is calculated as:

$\theta = -5 + 1*360$

$\theta = -5 +360$

$\theta = 355$

The equation p=100−4t represents the percent p of battery power remaining in an MP3 player after t hours.

fenix001 [56]

Answer:

Step-by-step explanation:

Here time (t) is the independent variable; power (p) is the dependent one.

The graph of p = 100 - 4t is a straight line with slope -4. 100 is the vertical intercept. Battery power begins at 100 and steadily decreases after that.
