Answer:
Step-by-step explanation:
Note that

and

.
From the unit circle, we can check that

and

have the same value, but opposite signs, that is:

.
Thus,

.
Note that

is the x-coordinate of the lowest point on the unit circle, that is (0, -1). Thus

Answer: 0
Answer:
4
Step-by-step explanation:
6x + 5x+2 + 134 = 180 All triangles have 3 angles = 180. Combine
11x + 136 = 180 Subtract 136
11x = 180 - 136
11x = 44 Divide by 11
x = 44/11
x = 4
=======================
Angles are
5x + 2 = 22
6x = 24
<3 = 134
Total = 180
The probability of a head or tail upon flipping is 50-50. THe asnwers are as followsL
a. {HHH, HHT, HTT, TTT, TTH, THH, HTH, THT}b and c. p = 3C3 * 0.5^3 = 0.125d. from a, p = 3/8 = 0.375e. from a, p = 3/8 = 0.375f. 0.875
