Answer:

<h2>AB=8.4 inches</h2><h2>AC=13.05 inches</h2>

Solution,

\frac{ab}{bc}   = tan \: 40 \\ ab = bc \times tan \: 40 \\ ab = 10 \times 0.84 \\ ab = 8.4 \: inches \:

\frac{bc}{ac}  = cos \: 40 \\  \frac{bc}{cos \: 40}   = ac \\ ac =  \frac{10}{cos \: 40}  \\ ac = 13.05 \: inches

Hope this helps...

Good luck on your assignment..

Each unit on a coordinate plane represents 1 mile. One end of the road starts at (212,23). The road ends at (6,23). How long is
olya-2409 [2.1K]
Distance formula : sqrt (x2 - x1)^2 + (y2 - y1)^2
(212,23)...x1 = 212 and y1 = 23
(6,23)......x2 = 6 and y2 = 23
now we sub
d = sqrt ((6 - 212)^2 + (23 - 23)^2)
d = sqrt ((- 206)^2 + (0^2))
d = sqrt (42436 + 0)
d = sqrt 42436
d = 206 miles <==
