Answer:
q - p
Step-by-step explanation:
For complementary angles B and C, ...
cos(C) = sin(B) = p
sin(C) = cos(B) = q
Then the difference is ...
sin(C) -cos(C) = q - p
61.67$ because you round the 7 up to the nearest hundredth
Answer:
Step-by-step explanation:
let x and y be length and width of rectangle.
Perimeter=2(x+y)
area=xy
2(x+y)=1/2 xy
4(x+y)=xy
4x+4y=xy
x y-4y=4 x
y(x-4)=4 x
