5.01 Exact values in right-angled triangles
Write down the exact value of the following:
\sin 60 \degree
\cos 60 \degree
\tan 30 \degree
\sin 45 \degree
Given that \sin \theta = \dfrac{1}{2} in a right triangle:
State the value of \theta.
Hence, find \cos \theta.
Find the exact value of the pronumeral(s) in the following triangles:
Use exact values to solve for \theta in the following triangles:
Consider the following diagram:
If \angle EBA is 60 \degree, name two other angles that are also 60 \degree.
Given that CD has a length of 5 \sqrt{7}, calculate the exact values of m \text{ and }n.
Consider the figure shown:
Find the exact length of the following:
p
q
r
s
Hence, find the exact perimeter of the quadrilateral.
Consider the given shape:
Find x.
Find the exact value of y.
Hence, find the exact perimeter of the shape.
