Find the measure of the exterior angle. *

Step-by-step explanation:

✧ $\underline{ \underline{ \large{ \tt{S \: O \: L \: U \: T \: I \: O \: N}}} }:$

Set up an equation and solve for x :

⋆ $\large{ \bf{(4x + 9) \degree = 2x \degree + (3x - 12) \degree}}$ [ Exterior angle is always equal to the sum of two non - adjacent interior angles ]

~Remove the unnecessary brackets

⟶ $\large{ \bf{4x \degree + 9 \degree = 2x \degree + 3x \degree - 12 \degree}}$

~Add the like terms : 2x ° & 3x°

⟶ $\large{ \bf{4x \degree + 9 \degree = 5x \degree - 12 \degree}}$

~Move 4x to right hand side and change it's sign

~Similarly move 12 to left hand side and change it's sign

⟶ $\large{ \bf{9 \degree + 12 \degree = 5x \degree - 4x \degree}}$

⟶ $\large{ \bf{21 \degree = x \degree}}$

⟶ ${ \large{ \bf{x = 21 \degree}}}$

Now , Substituting the value of x in (4x+9)° [ Exterior angle ]

⤿ $\large{ \bf{4 \times 21 \degree + 9 \degree}} = \boxed{93 \degree}$

☥ $\boxed{ \boxed{ \large{ \tt{Our \: Final \: Answer : \boxed{ \underline { \tt{93\degree}}}}}}}$

Effectus [21]

The relation is y = x^3, for x > 0.
If you graph it, you'll see that it passes the vertical line test, so it is a function.
