Step-by-step explanation:

We know that all the angles of a triangle equal 180 when added together. So lets make an equation for this question.

(10x-10) + (10x+8) + 8x = 180

I just took all the angles and added them together to make 180. Now solve for x.

10x - 10 + 10x + 8 + 8x = 180 (combined like terms)

28x -2 = 180 (added 2 to both sides)

28x = 182 (divided both sides by 28)

x = 6.5

Answer:

$\frac{12 {z}^{ 3} {y}^{2} }{5 {x}^{ 2} }$

Step-by-step explanation:

We want to simplify:

$\frac{36 {x}^{ - 2} {y}^{2} }{15 {z}^{ - 3} }$

The trick is that when a negative index in the numerator comes to the denominator , it becomes positive.

The vice-versa is also true.

That is:

${a}^{ - n} = \frac{1}{ {a}^{ n} }$

and

${a}^{n} = \frac{1}{ {a}^{ - n} }$

We simplify to get:

$\frac{12 {z}^{ 3} {y}^{2} }{5 {x}^{ 2} }$

The last choice is correct.
