Step-by-step explanation:
4x + 5x = 90°
10x = 90°
x = 90°/ 10
x = 10 (<em>a</em><em>n</em><em>s</em>)
The value of n that will make the expression equal is 13
<h3>Equations and expression</h3>
Equations are expressions separated by equal sign
Given the equation
11n = 143
Divide both sides by 11 to have;
11n/11 = 143/11
n = 13
Hence the value of n that will make the expression equal is 13
