Find the “x” value in the triangle below.
x = 2√3
Find the x value in the triangle below.
x = 5
Create a Proof for the 45°-45°-90° Triangle Equation
- Establish that a 45°-45°-90° Triangle has two equal length sides.
- From that information we can Establish that in the Pythagorean Theorem, A = B, and we can Substitute one with the other.
- Simplify the equation and solve for A or B to determine that
A = B = (√2/2) C
or
(√2) A = (√2) B = C
Find the length of the unknown sides in the triangle shown below
hypotenuse = 8√2
Leg = 8
Create a proof for the sides of a 30° 60° 90° Triangle.
- Create an Equilateral Triangle and label all the sides and angles.
- Split the Equilateral Triangle down the middle and label the new sides and angles.
- Create an equation using the Pythagorean Theorem to find the missing side.
- Solve and Simplify the equation for the missing side “a.”
Solve for the missing side of the Triangle.
6√3
What is the Sin, Cos, and Tan of angle “F.”
Sin (F) = 12/13
