Acute Angle Triganometry

Question 1

Acute Triangle

Answer 1

This is a triangle with three acute angles ( less than 90).

Question 2

Sin Law

Answer 2

Sin( A ) / a = Sin( B ) / b = Sin( C ) / c

Question 3

Cos Law ( Finding Sides )

Answer 3

a^2 = b^2 + c^2 - ( 2bc * Cos( A ) )

Question 4

Cos Law ( Finding Angles )

Answer 4

Cos ( A ) = b^2 + c^2 - a^2 / 2bc
