Answer:
9
Step-by-step explanation:
Given,
Side of square = 3 feet.
To find : Area of square = ?
Formula : -
Area of square = ( side )²
Area of square
= 3²
= 3 x 3
= 9 feet²
Therefore,
The unit of it's area will be 9 feet².
Answer: It is D
Step-by-step explanation:
4x+5y=-35 will be that in standard form
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.
The answer is 12. theorem- in the above figure if bf is a perpendicular to ca then cf and fa are congruent
