Find the length of side AB, give your answer to 1 decimal place

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

1/4 because there is 4 grades.
