Answer:
AB = 26.5º
Step-by-step explanation:
cosA = adj/hyp
cosA = AC/AB
cos41 = 20/AB
Multiply both sides by AB
AB * cos41 = 20
Divide both sides by cos41
AB = 20/cos41
AB = 26.5º
Answer:
Explanation:
ΔABC is right in the angle ∠C
in this case AB is the hypotenuse of the triangle ABC
according to the given data we will use the length of AC which is the adjacent side to the angle ∠A and the Cosine of the angle ∠A in the following formula:
the hypothenuse = adjacent side / cosine of the angle
AB = 20 / cos(41°)
AB = 26.5
