Well, I can't figure out the answer at the moment, but I can give you a tip. Just substite each possible sign in the to see if one works... for example: +++, x+-, ++-....
Hope this helps you out :)
34% . <span>Since going from 75% to 82% is simply the right portion of that middle, the answer is half of 68%, or 34%.</span>
I assume the answer is 1/4
Answer:
65°
Step-by-step explanation:
To obtain Angle A, we use the cosine rule ;
Cos A = (b² + c² - a²) / 2bc
Cos A = (12² + 14² - 14²) / 2(12)(14)
Cos A = 144 / 336
A = Cos^-1(144/336)
A = 64.62°
A = 65°
