Answer:
W = 13.33
X = 13.10
Step-by-step explanation:
You use Trig
S = O/H. C = A/H. T = O/A
For W we have to find Adjacent using Opposite, so we're going to use Tangent
Now we have Tan = O/A and rearrange this to find Adjacent
Tan = O/A --> ATan = O --> A = O/Tan
then we plug in A = 12/Tan(42°) which gives us 13.3273.... I usually round up to the 2nd decimal, so 13.33
To find X we do the same thing with a little bit of additional work
Since we already did the work for the last one, we can just skip a few of those steps
A = 12/Tan(27°) which gives us 26.4322..... or 26.43
But that gives us the whole bottom bit, which is X+W, so just subtract the W
26.43 - 13.33 = 13.10
Sorry if I'm bad at simplifying my wording
I hope this is correct, my math seems right, but the picture is not to scale

The answer is x= -3. 0.7(-3)-1.4=-3.5
Using the speed - distance relationship, the time left before the appointed time is 27 minutes.
<u>Recall</u><u> </u><u>:</u>
<u>At</u><u> </u><u>10mph</u><u> </u><u>:</u>
- Distance = 10 × (t + 3) = 10t + 30 - - - (1)
<u>At</u><u> </u><u>12</u><u> </u><u>mph</u><u> </u><u>:</u>
- Distance = 12 × (t - 2) = 12t - 24 - - - - (2)
<em>Equate</em><em> </em><em>(</em><em>1</em><em>)</em><em> </em><em>and</em><em> </em><em>(</em><em>2</em><em>)</em><em> </em><em>:</em>
10t + 30 = 12t - 24
<em>Collect</em><em> </em><em>like</em><em> </em><em>terms</em><em> </em>
10t - 12t = - 24 - 30
-2t = - 54
<em>Divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>-</em><em> </em><em>2</em>
t = 54 / 2
t = 27
Hence, the time left before the appointed time is 27 minutes.
