Determine the missing value, x. Then, classify the triangle by side and by angle measure.
Question in below;

The value of x in the right angle triangle is approximately 45 degrees.
The angle of the right angle triangle can be found as follows:
Therefore, let's find the hypotenuse side using Pythagoras theorem,
6² + 6² = c²
c² = 72
c = √72
c = 8.48528137424
c = 8.5 cm
Hence,
sin x = opposite / hypotenuse
sin x = 6 / 8.5
sin x = 0.70588235294
x = sin⁻¹ 0.70588235294
x = 44.9006818301
x = 45°
