Answer:
x = 36°
Step-by-step explanation:
The interior angles of a triangle must add up to 180°.
Thus, 90° + 54° + x = 180°, or
144° + x = 180°. Subtracting 144° from both sides, we get x = 36°
The value of x in the triangle will be equal to 36°.
The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.
The interior angles of a triangle must add up to 180°.
90° + 54° + x = 180°, or
144° + x = 180°. Subtracting 144° from both sides, we get
x = 36°
Therefore the value of x in the triangle will be equal to 36°.
