Answer:

Option "A" is correct.

Step-by-step explanation:

As we know that a line perpendicular to another line always makes right angle (i.e. 90°) with that line, which in this case is equal to the total angle of 6X and 4X.

THUS .:

6X +4X = 90°

=> 10X = 90°

=> X = 90/10 = 9

Answer:

The correct option is A) 9.

Step-by-step explanation:

Consider the provided figure.

We need to solve find the value of x.

By Analyze the diagram we can concluded that:

[tex]6x+4x=90[/tex]

Now add the like terms as shown:

[tex]10x=90[/tex]

Divide both the sides by 10.

[tex]\frac{10x}{10}=\frac{90}{10}[/tex]

[tex]x=9[/tex]

Hence, the correct option is A) 9.
