Answer 1

Answer: Angle O = 70.5°

Step-by-step explanation: The triangle given in the question shows two sides which are 6 and 4.5

Also we have side 4.5 with an opposite angle which is 45° and side 6 with an opposite angle which is unknown.

In view of what we have available, we shall use the Sine Rule which states that

a/SinA = b/SinB = c/SinC

Hence we can express this as

4.5/Sin 45 = 6/Sin O

By cross multiplication we now have

4.5 x Sin O = 6 x Sin 45

Sin O = (6 x Sin 45)/4.5

Sin O = (6 x 0.7071)/4.5

Sin O = 4.2426/4.5

Sin O = 0.9428

By using tables of values or a calculator

Angle O = 70.5272

Angle O is approximately 70.5°
