Find the measure of angle N. A. 150° B. 8° C . 90° D. 294°

oee [108]

Answer:

$\angle N=150\degree$

Step-by-step explanation:

The sum of interior angles of a 5-sided polygon is 540 degrees.

We sum all the angles to get:

<M+<L+<N+<O+<P=540

90+90+(17x+4)+(18x+6)+(10x-10)=540

45x+180=540

45x=540-180

45x=360

x=8

N=18*8+6

$\angle N=150\degree$

LITTERLY HELP ME PLEASEE..... 2/x-4x/2x-3=-2 PLEASEE I INSERTED A PIC

Stels [109]

Answer:

x = -3

Step-by-step explanation:

Given expression is,

$\frac{2}{x}- \frac{4x}{2x-3}=-2$

$\frac{2(2x-3)}{x(2x-3)}-\frac{4x(x)}{x(2x-3)}=-2$

$\frac{2(2x-3)-4x^{2} }{x(2x-3)}=-2$

(4x - 6) - 4x² = -2x(2x - 3)

4x - 6 - 4x² = -4x² + 6x

4x - 6 = 6x

6x - 4x = -6

2x = -6

x = -3
