Answer:
Wheres the picture?
Step-by-step explanation:
The Law of Cosine states
cos
so plugging in the numbers gives us
cos
We now have cosJ so plug that into your calculator and find arccos (arccos(cos(J)) = J)
arccos
rounding your answer will give you 34°
Answer:
77 weeks
Step-by-step explanation:
Let the number of weeks be represented as x
The equation for the above question is given as:
146 + 2(x) = 300 pieces
146 + 2x = 300
2x = 300 - 146
2x = 154
x = 154/2
x = 77

Answer:
Complementary, x=60.
Step-by-step explanation:
The angles are complementary because they add up to 90 degrees, opposing supplementary angles, which add up to 180 degrees. To find x, we need to form an equation to represent the problem. We know the two angles add up to 90 degrees, so we can use that to make the equation.
(x-30)+x=90 Simplify.
x-30+x=90
2x-30=90 Add 30 to both sides.
<u>+30 +30</u>
2x=120 Divide both sides by 2.
x=60
We can also find the value of the angles by plugging in x.
Angle 1: (x-30)
(60-30)
30 degrees
Angle 2: x
60 degrees
(You can also notice that the two angles add up to 90 degrees, which is another way of telling that the angles are complementary.)
