Answer:
5.6 = AB
Step-by-step explanation:
Since this is a right triangle, we can use trig functions to find the length of AB
Cos theta = opp side/ hypotenuse
cos 62 = AB / BC
cos 62 = AB /12
Multiply each side by 12
12 cos 62 = AB
5.633658753 = AB
Rounding to 1 decimal place
5.6 = AB
We can also find AC
sin theta = opp side/ hypotenuse
sin 62 = AC / BC
sin 62 = AC /12
Multiply each side by 12
12 sin 62 = AC
10.59537111 = AC
Rounding to 1 decimal place
10.6 = AC
