Answer:
117. I'm guessing that the x stands for multiplication not a variable.
Step-by-step explanation:
Multiply using the distributive property and then combine the like terms.
Note that
(4sqrt3)^2 = (2sqrt3)^2 + 6^2 [ 48 = 12 + 36] so the triangle is a right angled one with hypotenuse AB
So angle C = 90 degrees
sin A = 2 sqrt3 / 4 sqrt3 = 1.2 giving A = 30 degrees
and B = 90 - 30 = 60 degrees
A = 30, B = 60 and C = 90 degrees
A=P(1+rt)
A/P=1+rt
A/P-1=rt
AP-P/Pr = t
A-1/r=t
Answer:
Step-by-step explanation:
Since the diameter is 2.1 then its radius is 1.05.
Therefore the circumference is 
.
ITS IS 8x-7y-5z=15 I THINK'
