Question

In KLM the measure of

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

∠ M = 90

∠ K = 78

KL = 35 ft

MK = ?

Step 02:

cos α = adjacent / hypotenuse

α = 78

adjacent = MK

hypotenuse = KL = 35

cos 78 = MK / 35

35 * cos 78 = MK

7.277 = MK

The answer is:

MK = 7.3 ft
