Answer:
B
Step-by-step explanation:
so for 4x-3y=9 and 2x+6y=5
the answers for x and y are 23/10 and 1/15 respectively.
so we can just check the values for each equation by inserting x or y to solve it the quickest.
and the only problem where the solutions line up is B
Hope that helps :)
29yd is the answer to your question
Its a right angle triangle, so use trigonometry.
Since the adjacent and hypotenuse is given use cos .
Answer:
