<h3>
Answer: x = 14.3</h3>
=========================================================
Explanation:
We can find x using the law of sines, but first we need to find the missing angle. Let's call that y for now. The three angles of any triangle add to 180, so,
23+146+y = 180
169+y = 180
y = 180-169
y = 11
The missing interior angle is 11 degrees.
-----------
Now we can apply the law of sines.
sin(23)/x = sin(11)/7
7*sin(23) = x*sin(11)
x*sin(11) = 7*sin(23)
x = 7*sin(23)/sin(11)
x = 14.3343236728824
x = 14.3
Make sure your calculator is in degree mode.
Answer:
Step-by-step explanation:
If train arrives between 2:00 to 3:00 (60min) and waits for 20 min and leaves, probability of finding train in that 60 min is 
.
Probability of finding John is 
can arrive any minute.
now the probability of finding both john and train is *
=.
This is compound Probablity Problem.
You see the c next to the 27 plug in 2/3 for it so u would get 10(27(2/3)+8)
Answer:
<h3>i2 = -1</h3>
Step-by-step explanation:
5i ⋅i⋅(−2i)= −
10 ⋅ i2 ⋅ i= − 10 ⋅ (−1) ⋅ i = 10i
