I NEED HELP !! PICTURE IS UP THERE ^

Fynjy0 [20]

Answer:

$\angle 1 = 99^\circ$

$\angle 3 = 99^\circ$

$\angle 4 = 81^\circ$

Step-by-step explanation:

Given

$\angle 2 = 81^\circ$

Required

Determine: $\angle 1 . \angle 3 , \angle 4$

Solving for $\angle 1$ , we have:

$\angle 2 + \angle 1 = 180^\circ$ --- angle on a straight line

So, we have:

$\angle 1 = 180^\circ-\angle 2$

$\angle 1 = 180^\circ-81^\circ$

$\angle 1 = 99^\circ$

To solve for $\angle 3, \angle 4$ , we have:

$\angle 3 = \angle 1$

$\angle 4 = \angle 2$ --- Vertically opposite angles

So:

$\angle 4 = 81^\circ$

$\angle 3 = 99^\circ$

Simplify each cube root expression. Describe the simplified form of the expression as rational or irrational. In your final answ

Margarita [4]

Answer:

$\sqrt[3]{81}=3\sqrt[3]{3}$
$\sqrt[3]{-64}=-4$

Step-by-step explanation:

$\sqrt[3]{81}=\sqrt[3]{3^4}=\sqrt[3]{(3^3)(3)}=3\sqrt[3]{3}$

This is irrational.

$\sqrt[3]{-64}=\sqrt[3]{(-4)^3}=-4$

This is rational.

_____

Please be aware that 3 square root of 81 is not the same as cube root of 81.

$3\sqrt{81}\ne\sqrt[3]{81}$

You can call a cube root what it is.
