Answer:
a = 9.2
b = 8.65
Step-by-step explanation:
First Question
To find a we use sine
sin ∅ = opposite / hypotenuse
a is the opposite
12.8 is the hypotenuse
sin 46 = a / 12.8
a = 12.8 sin 46
a = 9.2
Second question
To find b we use cosine
cos∅ = adjacent / hypotenuse
b is the adjacent
16.8 is the hypotenuse
cos 59 = b / 16.8
b = 16.8 cos 59
b = 8.65
Hope this helps you
