Answer:
The awnser is D hope this helps :)
Step-by-step explanation:
P-4(p-2(3-p))=12 remove the parentheses
P-4(p-6+2p)=12 collect like terms
P-4(3p-6)=12 remove the parentheses
P-12p+24=12 collect like terms
-11p+24=12 move the constant to the right
-11p=12-24 calculate
-11p=-12 divide both sides
P=12/11
Alternative form
P=1 1/11
Answer:
76 unit
Step-by-step explanation:
because added the rectangle size and added the 60 with 16
cos(20) = sin(70)
note how 20+70 = 90
The general rule is that if x+y = 90, then cos(x) = sin(y). The rule works in reverse as well. Another way to phrase the rule is cos(x) = sin(90-x).
So,

Note: if the computer doesn't like the answer of "sin 70" then try "sin(70)" and see how that works out. It's also possible that the teacher wants the single numeric value of "70" in the first box rather than the "sine" part to go along with it. Though that would be strange and incorrect since cos(20) = 70 is a false statement.
