Question

Triangle ABC is a right triangle and cos(22.6)=b/13. Slobs for b and round to the nearest whole number

Answer 1

Answer
12


Step-by-step explanation
Cosine is the ratio of adjacent to hypotenuse.

So, in this case b is the adjacent and 13 is the hypotenuse.

cos22.6 = b/13
b = 13×cos22.6
= 13×0.923879532
=12.010

To the nearest whole number the answer is 12.
