3. Triangle ABC has angle measures as shown.
Angle a = (3x)°
Angle b = (4x - 1)°
Angle c = Not Shown
(a) What is the value of x? Show your work

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 , and 90. The sum of these values is 180. So

So the value of angle x is 13°.
