My guess is (C
that could be the total number
Answer: 48cm
Step-by-step explanation:
Using the formula
P=2(l+w)
Solving for l
l=P
2﹣w=120
2﹣12=48cm
I think that the length of DE is 4. you can add 0.5 to each side of BC in order to find the length of EF since EF starts 0.5 before BC does and therefore also ends 0.5 after BC since the circle is symmetrical.
Answer:
A, C
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
the ∠A is adjacent (adj) to AB and opposite (Opp) of BC and AB is the hypotenuse (Hyp) of the triangle
which one of the above trig functions fits that?
sin(Ф) = BC / AC is sin(Ф)= Opp / Hyp , so choice A) works
cos(Ф) = BC / AC is not cos(Ф) = Opp / Hyp so choice B) does not work
cos(Ф) = BA / AC is cos(Ф) = Adj / Hyp so choice C) works
AC / BC is just a ratio it's not the angle , so D) doesn't work
The next larger ten is . . . . . . 50 .
The next smaller ten is . . . . . . 40 .
. . . . . . 49 is closer to . . . . . . 50 than it is to . . . . . . 40 .
So the nearest ten is . . . . . . 50 .
