Answer:

$x+y = 10$

Step-by-step explanation:

$~~~\dfrac{53}{17}\\\\\\=3 \dfrac{2}{17}\\\\\\=3+ \dfrac{2}{17}\\\\\\=3+\dfrac{1}{\tfrac{17}2}\\\\\\=3+\dfrac{1}{8\tfrac 12 }\\\\\\=3+ \dfrac{1}{8+ \dfrac 12 }\\\\\\\text{By comparing with}~ 3 + \dfrac 1{x + \tfrac 1y},~ \text{we get}~ x = 8~ \text{and}~ y = 2.\\\\\text{Hence,}~ x +y = 8+2 =10.$

4x + 2x = < y

This is because the opposite sides (which is 4x and 2x) of a triangle add up to the exterior angle (<y).

We have to find X.

As you know:

$3x + 4x + 2x = 180$

because the angles of a triangle add up to 180.

When we add them:

$9x = 180$

$x = \frac{180}{9}$

The 9 is multiplying with the X. We want X only and not 9 with it. So, when we take 9 to the other side, it becomes divide. As a result, the answer to x is:-

$x = 20$
