To solve this question we must first find out what is x.

X + x - 4 = 82 degrees

2x - 4 = 82

2x = 86

X = 86/2 = 43.

Here x would be 43 degrees.

We can add up the angles because we know the angle of DAC and the CAB angle add up to give 82 degrees.

Vikki [24]

Answer:

x= 616326743 / 31419696919

Step-by-step explanation:

62839393838x = 1232653486

Let's solve your equation step-by-step.

62839393838x=1232653486

Step 1: Divide both sides by 62839393838.

62839393838x / 62839393838 = 1232653486 / 62839393838

x= 616326743 / 31419696919

What is the measure of the central angle of a circle with radius 15 ft that intercepts a 10 ft arc?

olga2289 [7]

L=10ft
R=15ft
We have to find theta

$\Large{\underline{\sf Solution:-}}$

$\\ \sf\dashrightarrow L=\dfrac{\Theta}{180}\times \pi r$

$\\ \sf\dashrightarrow 10=\dfrac{\Theta}{180}\times 3.14\times 15$

$\\ \sf\dashrightarrow 10=\dfrac{\Theta}{180}\times 47.1$

$\\ \sf\dashrightarrow \Theta=\dfrac{10(180)}{47.1}$

$\\ \sf\dashrightarrow \Theta=\dfrac{1800}{47.1}$

$\\ \sf\dashrightarrow \Theta=38.2°$

A used-car dealer has a vehicle on the lot with a sticker price of $5999. If the

Digiron [165]

Answer:

$4999

Step-by-step explanation:

Let the cost of the car be x

<u>Then considering 20% markup, the sticker price is:</u>

x + 20% = 5999

<u>Since 20% of x is 20/100x = 0.2x,</u>

x+ 0.2x = 5999
1.2x = 5999
x = 5999/1.2
x ≈ $4999

<u>So dealer paid</u> $4999 for the car

Janelle types at the rate of Syntax error from line 1 column 49 to line 1 column 73. Unexpected 'mathsize'. Of a page per minute

Lesechka [4]

Answer: D) Janelle can type 1/4 of a page in 2/3 of a minute

Step-by-step explanation:

Option A is wrong because based on the constraints, Janine would type less than 3/8 of a page in anything less than a minute. 8 > 3/8.

For that same reason, option B is wrong as well. 2 > 3/8.

1/2 > 3/8 so Option C is wrong for the same reason as the options above.

To test option D;

If Janine can type 3/8 of a page per minute, how much can she type in 2/3 minutes.

Assume the much she can type is x;

3/8 : 1

x : 2/3

1x = 3/8 * 2/3

x = 1/4

<em>Option D is therefore correct. </em>
