Chapter 8: Applications of Trigonometric Functions

Find the remaining angle(s) and side(s) of each triangle, if it (they) exists. If no triangle exists, say “No triangle.”$c=5,b=4,A=70$

In the given problem solve the triangle using the law of sines :$A=70°,B=60°,c=4.$

Find the exact value of the expression-

$\tan 12°-cot78°$

Find the area of a triangle whose sides are$a=4.b=5,c=3$.

the displacement d (in meters) of an object at time t (in seconds) is given$d=4+3\sin \left(\pi t\right)$

Solve each triangle.

$a=6b=4,C=60°$

Find the area of each triangle.

Find the area of a triangle whose sides are $a=2,b=2,c=2.$

Find the exact value of the expression-

$\frac{\cos 10°}{\sin 80°}$

Solve each triangle.

$a=3,c=2,B=110°$
