Answer:
sin(-π/6) = -1/2
Step-by-step explanation:
sin(π/6) = 1/2 is a value we have memorized.
sin(-π/6) = -sin(π/6) = -1/2
Answer:
a=1 because 3x means 3 multiply 2 and it is substracted from 7 and 7-6 is 1
b=3
c=9
Step-by-step explanation:
hope you will understand from the explanation of a
1.10 = x + y
x = 1 + y
subtract 1
.10
x = y
.10
the answer is .10
Answer:
83.9°
Step-by-step explanation:
Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.
a= 13 cm
a2= 169cm
b= 4cm
b2=16 cm
a2+b2= 185cm (c2)
c=13.6cm
after wards use the law of cosines and c= 83.9°
Answer:
42 ounces
Step-by-step explanation:
10^2 is equal to 100.
So how many ounces in 100 bottles?
