5. 27.29°
6. 38.21°
Step-by-step explanation:
Given:
Δ ABC is right angle at A
Δ PQR is right angle at Q
Δ XYZ is right angle at X
To find:
∠ C = ?
∠ P = ?
∠ Z = ?
Solution:
For 4.)
We Know the Identities,
∴
For 5.)
For 6.)
C is 0.003 and so is a and so is b
Sector area = (central angle / 360) * PI * radius^2
