Sine Function and Angle Calculation

The video tutorial explains how to find an angle in a right angle triangle using the SOH formula. It begins by identifying the sides of the triangle, then applies the sine function to calculate the angle. The process involves using the sine inverse function to determine the angle value, which is then verified using a calculator.

What type of triangle is being discussed in the video?

• Equilateral triangle

• Isosceles triangle

• Right angle triangle

• Scalene triangle

What is the goal of the problem presented in the video?

• To find the perimeter of the triangle

• To find the size of angle X

• To find the length of the hypotenuse

Which side is opposite to the angle X in the triangle?

• Opposite side

• Base

• Adjacent side

• Hypotenuse

What is the hypotenuse in a right angle triangle?

• The side adjacent to the angle

• The side opposite the angle

• The shortest side

• The longest side

Which trigonometric function is used in this problem?
