Answer:
B is correct option
Step-by-step explanation:
The correct option is B:
Convert 3 1/2 inches in feet by proportion:
3 1/2 = 7/2
1/4 / 7/2 = 1/x
1/2 / 7 =1/x
1/2 *x = 7
x= 7*2
x= 14ft
Convert 5 1/2 into feet
5 1/4 = 21/4
1/4 / 21/4 = 1/y
THE DENOMINATORS WILL BE CANCELLED OUT BY EACH OTHER.
1/21 = 1/y
y = 21ft
Therefore it is 14ft by 21ft, which is option B....
Given sin (13y-5) = cos (2y+5)
We have a formula regarding complementary angles that is given as follows :-
If sin(A) = cos(B), then A + B = 90 degrees.
where A and B are complementary angles.
Comparing it with given information, we get A = (13y-5) and B = (2y+5).
So the sum of two angles A = (13y-5) and B = (2y+5) would be 90 degrees.
(13y-5)° + (2y+5)° = 90°
13y + 2y - 5 + 5 = 90°
15y = 90°
y = 6°
Hence, final answer is y = 6 degrees.
