Try this solution:
according to the rule sin(90-y)=cos(y), it is possible to re-write the given equation:
sin(90-y)=cos53°, where 90-y=x.
Then substituting the value y=53° into the equation 90-y=x, it is possible to find the 'x': 90-53=37°.
answer: 37°
The answer is 1.34 . if you round it then its 1

Step-by-step explanation:
3 rows of corn provided 270 ears.
therefore 1 for provides 270/3 = 90 ears
so, to get 360 ears of corn, we need 360/90 = 4 rows of corn.
Answer:
The correct option is III: 4.5 cm.
Step-by-step explanation:
The area of a square is the following:
(1)
Where:
A: is the area
b: is the side of the square
We have that the area is 20 cm², hence by solving equation (1) for <em>b</em> we can find the side:
Therefore, the correct option is III: 4.5 cm.
I hope it helps you!
