Respuesta :

The value of x is 13°.

Step-by-step explanation:

Step 1:

The angle made by any right angle is 90°. So angle C is 90°.

The total angle made by a triangle is always 180°.

The sum of all three angles in a triangle is 180° for any triangle formed.

Step 2:

The angles of the given triangle are [tex]3x[/tex], [tex]4x-1[/tex] and 90. The sum of these values is 180. So

[tex]3x+(4x-1)+90 = 180, 7x + 89 = 180.[/tex]

[tex]7x= 180-89 = 91, x = \frac{91}{7} = 13.[/tex]

So the value of angle x is 13°.
