Answer:

x = 120

Step-by-step explanation:

All three angles are marked as equal. There are two ways to find x.

Method one

Find the supplement to x

Let the supplement to x be y

y + y + y = 180

3y = 180 Divide by 3

y = 180/3

y = 60

=================

A straight line has an angle of 180 degrees.

x + y = 180 Substitute y = 60 into the equation

x + 60 = 180 Subtract 60

x = 180 - 60

x = 120

Method 2

The two angles not connect to x are called remote interior angles. These two angles are equal to x.

x = 60 + 60

x = 120

Easiest way to calculate 22% mark up from a cost of say 39.99

satela [25.4K]

Answer:

The markup amount on the cost 39.99 $ will be: 8.78 $

Step-by-step explanation:

Given

The cost = 39.99 (Let say in $)

Mark up = 22%

22% = 0.22

The markup of 22% on the cost can be calculated by multiplying the cost by 22% or 0.22

Markup amount = 0.22 × 39.99

= 8.78 $

Therefore, the markup amount on the cost 39.99 $ will be: 8.78 $

Help please ASAP please I’ll mark you as brainlister

storchak [24]

Answer:

a = 4

Step-by-step explanation:

$\sin(theta) = \frac{opposite}{hypotenuse}$

$\cos(theta) = \frac{adjacent}{hypotenuse}$

$\tan(theta) = \frac{opposite}{adjacent}$

hypotenuse = a

opposite = 2√3

adjacent = b

theta = 60°

the best formula to use is the first formula cause we have all the values to substitute in it in order to find the value of a

$\sin(60) = \frac{2 \sqrt{3} }{a}$

$\frac{2 \sqrt{3} }{ \sin(60) } = a$

$4 = a$

$a = 4$

Help<br><br> (5a-3a^3)*(4a-1)

ivann1987 [24]

Answer:

$-12a^{4} + 3a^{3} + 20a^{2} -5a$

Step-by-step explanation:

$(5a-3a^{3} )$ • $(4a-1)$

Let's use FOIL (first, outer, inner, last) to solve this. We'll multiply the terms by one another in that fashion.

$20a^{2} - 5a - 12a^{4} + 3a^{3}$

Rearrange in decreasing exponents.

$-12a^{4} + 3a^{3} + 20a^{2} -5a$
