2. A boat is crossing the river as shown. To the nearest tenth of a degree, find the angle at which the boat must head upriver in order to travel directly across the river. The diagram is not drawn to scale. https://www.connexus.com/content/media/456845-2232011-25832-PM-87452468.png A. 70.3 north of west B. 19.7 north of west C. 19.7 south of west D. 70.3 south of west

do you go to connections?
what
do you go to connections academy?
no im home schooled
could you help me with a few more?
sure
post them
3. find the angle of elevation of the sun from the ground to the top of a tree when a tree that is 10 yards tall casts a shadow 14 yards long. round to the nearest degree.
@blake57roger
T[,90 degree right angle,,10 height,14 shadow,] The angle B can be found using the inverse tangent function. B=ata((opp)/(adj)) Substitute in the values of the adjacent (14) and opposite (10) sides to angle B of the triangle. B=ata((10)/(14)) Take the inverse tangent of (10)/(14) to get 0.6202. B=0.6202 radians To convert radians to degrees, multiply by (180)/(`), since a full circle is 360^(o) or 2` radians. B=0.6202*(180)/(`) degrees Multiply 0.6202 by (180)/(`) to get (111.6449)/(`). B=(111.6449)/(`) degrees ` is approximately equal to 3.1416. B=(111.6449)/(3.1416) degrees Divide 111.6449 by 3.1416 to get 35.5377. B=35.5377 degrees
did that help
yes thanks! im about to post another one

Describe the vector as an ordered pair. Round the coordinates to the nearest tenth. https://www.connexus.com/content/media/456845-2232011-30120-PM-61314579.png The diagram is not drawn to scale.
hey is the web site so i can see it
ok ill draw it
be cause it says i have to log on
|dw:1392910345095:dw|
what your anwer choises
-58.1, 50.5 -102, 117.4 -117.4, 102 -50.5, 58.1
i cant pick between a and d what do you think
ummm d?
ill right go with that any more problems
yea
post them
use compass directions to describe the direction of the vector. the diagram is not drawn to scale.
ill draw it
