In triangle ABC angle c = 180-78-40 = 62 degrees
For the triangles to be congruent angle z must equal angle C
Solve for x:
2x + 8 = 62
Subtract 8 from both sides:
2x = 54
Divide both sides by 2:
X = 27
Now we k ow x has to equal 27 to be concurrent so we can answer the 3 questions.
A. False
B. True
C. True
Answer:
Step-by-step explanation:
In the rectangular complex number -9√3 + 9i, which has a standard form a + bi, the a = -9√3 and the b = 9. We need this in polar form (r, θ) where
and filling in:
(notice we do not put the i in there with the 9).
so
r = 18. Now let's move on to the angle, which is a little more difficult. The angle is found in the inverse tangent ratio:
so filling that in, we have:
Since tangent is the side opposite over the side adjacent, y is positive and x is negative in the second quadrant. This is a 30 degree angle in QII, which has a reference angle of 150 degrees. This angle in radians is 
, so the polar form of that number is (18, 
)
A. 15 tyres, 3 batteries.
b. 6 + 9 = t
2 + 1 = b
t = 15
b = 3
Answer:
52
Step-by-step explanation:
The split them up part is suppose to trick you, for there are still a total of 54 people cheering. So you do 54-2 since 2 people left and you have 52 still cheering.
