Question

Please Help Me! What is cos B?

Answer 1

Answer:

cos B = 0.4706

Step-by-step explanation:

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

 $cos B = \frac{adjacent}{hypotenuse}\\\\cos B = \frac{8}{17} \\\\cos B = 0.4706$

Answer 2

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

Option B
