Quadilateral inside circle follow these rules

sum of opposite angles is 180

so

B + D = 180

C + A = 180

x + 116 = 180

x = 180-116 = 64

A = 2×64 -40 = 128 -40
A = 88

Answer:

88°

Step-by-step explanation:

Angles B and D are supplementary, so the value of x is ...

x = 180° -116° = 64°

Then the measure of angle A is ...

(2x -40)° = (2·64 -40)° = 88°

The measure of angle A is 88°.

Fraction that less than 5/6 and has a denominator of 8

AnnyKZ [126]

A fraction that is less than 5/6 and has a denominator of 8 would be 4/8 because if you compare 4/8 and 5/6 4/8 is less than 5/6. (to compare this two fractions you need to make them have the same denominator so they would end up been 4/8=12/24
5/6=20/24
And 12/24 is smaller than 20/24
(Besides 4/8 is half and 5/6 is more than half

Can I get some help, it is due in 15 minutes and I need help. Thanks, any help appreciated

koban [17]

Well, I'm way past the 15 min mark, but here's how to do the question.

With this, you will need to use the distance formula, $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ , on XY, YZ, and ZX.

XY: $\sqrt{(3-1)^2+(1-6)^2}$

Firstly, solve inside the parentheses: $\sqrt{(2)^2+(-5)^2}$

Next, solve the exponents: $\sqrt{4+25}$

Next, solve the addition, and XY's distance will be √29

(The process is the same with the other 2 sides, so I'll go through them real quickly)

YZ:

$\sqrt{(6-3)^2+(3-1)^2}\\ \sqrt{(3)^2+(2)^2}\\ \sqrt{9+4}\\ \sqrt{13}$

ZX:

$\sqrt{(1-6)^2+(6-3)^2}\\ \sqrt{(-5)^2+(3)^2}\\ \sqrt{25+9}\\ \sqrt{34}$

Now that we got the 3 sides, we can add them up: $\sqrt{29}+\sqrt{13} +\sqrt{34} =14.8$

In short, your answer is 14.8, or the second option.

How can I find list price, selling price, and the discount?

solong [7]

List price is the price which is showcased for users for the purpose of customers to buy.

List price may be above or below the cost price of the item as per the need of the seller.

Selling price is the price at which an item is sold by the seller. Selling price can be different from list price as there may be discount from the list price.

Selling price above or below cost price is required to find profit or loss on the item.

Discount is the percent deduction on the list price or selling price which is offered to the customer to buy a particular item. Discount is usually less than selling price or list price as it is a depreciation from the actual value.

Disclaimer: No value has been provided for the calculation of the value and hence definition has been given.
