x = 36

Step-by-step explanation:

The angles 4x and x are supplementary, meaning they add up to 180; therefore we have

$4x + x = 180$

$5x = 180$

dividing both sides by 5 gives

$x = 36$

the measure of angle x is 36 and that of 4x is 4 * 36 = 144

The angle opposite to 4x also measures 144 and the one opposite to x is 36.

Answer:

x° + 4x° = 180°

5x° = 180°

x° = 180°/5

A box has a base of 12 inches by 12 inches and a height of 30 inches. What is the length of the interior diagonal of the box? Ro

Wittaler [7]

The sides of the box are 12in by 12in by 30in.

The interior diagonal =[12^2+12^2+30^2]0.5

=[144+144+900]^0.5

=1188^0.5

The final answer is 34.47in.

My deepest apology if this is not what you meant.

= 34.47in.

10% of the 50 were red.

Last Question

Because this may not be the question you want, I'll omit the first step which should be done with latex. The key to all of these except C is to invert the second fraction (turn the second fraction upside down) and multiply.

$\dfrac{6}{5} * \dfrac{-2}{3}$

=(6*-2) / (5*3) = - 12/15 = -4/5

$\dfrac{7}{4} *\dfrac{5}{3}$

= (7*5) / (4*3) = 35 / 12 = 2 11/12

Impossible to do 4/0 cannot be done.

$\dfrac{-2}{3} /\dfrac{-5}{4}=\dfrac{-2}{3} *\dfrac{-4}{5}$

= (-2*-4)/(3*5) =

8/15
