Answer:
Step-by-step explanation:
formula
d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
Givens
x2 = 2
x1 = - 7
y2 = -6
y1 = - 6
Solution
d = sqrt( (2 - - 7)^2 + (-6 - - 6)^2 )
d = sqrt( 9^2 + (-6 + 6)^2 )
d = sqrt(9)^2
d = 9
Answer:
cos²x.sec²x =1 (formula)
cos and sec are reciprocal to each other
cos²x=1/sec²x
now from the eq above,open the brackets and multiply
1-cos²2x
sin²2x
ANSWER: 114ft^2
Area of cabinets = (4*2)+(4*2) = 16ft^2
Area of kitchen = (10*13) = 130ft^2
Subtract area of the cabinets from total area
130ft^2 - 16ft^2 = 114ft^2
