Chapter 3 Understanding Quadrilaterals Exercise 3.2
Question 1.
Find x in the following figures.
Solution:
(a) We know that the sum of all the exterior angles of a polygon = 360°
125° + 125° + x = 360°
⇒ 250° + x = 360°
x = 360° – 250° = 110°
Hence x = 110°

# How do you solve 6/x+2>=0 using a sign chart?
Nov 9, 2016
$x \le - 3 , x \ge 0$
#### Explanation:
First solve the inequality as if it were an equality:
$\frac{6}{x} + 2 = 0$
$\frac{6}{x} + \frac{2 x}{x} = 0$
$\frac{2 \left(x + 3\right)}{x} = 0$
Set the numerator equal to zero to find where the function inters... |
