Draw Triangles With Given Sides

Determine whether it is possible to draw a triangle with sides of the given measures. 20cm, 12cm, 30cm.

Find the measure of the indicated angle (?) round to the nearest tenth.

Find the length of side w.

Select all choices which could be the measure of the sides of a triangle.

Draw the following triangle and label the sides (a,b,c) and their corresponding opposite angles (A,B,C).  A = 58⁰, B = 76⁰  and  c = 8, using your diagram decide which rule to use and find the size of angle C.

What is the length of side x?

Find the length of side AC

Use the Cosine rule to find the size of angle x. 

Draw the following triangle and label the sides (a,b,c) and their corresponding opposite angles (A,B,C). 
A = 58⁰, B = 76⁰  and  c = 8, use the Sine rule to find the length of side a.
