Simplify fully A) X^7 / X^3 B) Y^5 / Y^4

DENIUS [597]

Hi,

$\frac{x^{a} }{x^{b} } =x^{a-b}$

$\frac{x^{7} }{x^{3} }= x^{7-3} = x^{4}$

$\frac{y^{5} }{y^{4} } = y^{5-4} = y^{1} = y$

Find the value of x pls help

4vir4ik [10]

Answer:

x = 15°

Step-by-step explanation:

First Identify the angle of x by subtracting 180° - 120° = 60°

Always remember when you see a straight line the line measures 180°

So the angle of x = 60° but not the value of x so use the given equation to find the value of x

3x + 15 = 60°

3x - 15 = -15°

3x = 45

x = 15°
