In ABC, calculate AB to the nearest centimeter given that A = 57

2070 cm

Step-by-step explanation:

For this problem, we need to use the trigonometric functions: sine, cosine, and tangent.

Since we know ∠A is 57°, we know 57 is our angle. Since we are given AC and we are looking for AB, we can use cosine.

We need to convert 38 m into cm because that is the unit of answer.

38m=3800

*Make sure your calculator is in degrees. If you have it in radians, you will get another answer.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
