In a right triangle, ABC, with right angle C, find the indicated part. Round your answer to the nearest 0.1 degree. Find A, if a=10 m and c = 12 m. Answer 56.4 Degrees, 39.8 Degrees, 38.4 Degrees, 58.4 degrees
Added by Ronnie V.
Step 1
Here, we know the lengths of sides a and c. Second, we can use the trigonometric function cosine to find angle A. The cosine of an angle in a right triangle is equal to the length of the adjacent side divided by the length of the hypotenuse. So, cos(A) = Show more…
