Question

Please Help Me! What is cos B?

Answer 1

• cosØ=Base/Hypotenuse
• cosB=BC/AB
• cosB=8/17
• cosB=0.4706

Option B

Answer 2

cos B = 0.4706

Explanation:

The cosine of an angle in a right-angled triangle is the ratio of its adjacent side and the hypotenuse, so:

`cos B = (adjacent)/(hypotenuse)\\\\cos B = (8)/(17) \\\\cos B = 0.4706`
