11°<x°<58°
Step-by-step explanation:
first find out how much x can be by using 180 degrees.
(5x+3)°+(5x+3)°+58=180°
(10x+6)°+58°=180°
10x°+64°=180°
10x°=116°
x=11.6°

Correct option is A) [-13/4, 9/4] .
<u>Step-by-step explanation:</u>
Here we have following equation as |2 + 4x| = 11 or ,
. We need to solve for the value of x .Let's find out:
We know that Modulus Function is both positive & negative for particular values of x , i.e.
|2 + 4x| is positive :
⇒ 
⇒ 
⇒ 
⇒ 
|2 + 4x| is negative :
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , Correct option is A) [-13/4, 9/4] .
