Let us find the slopes of the two lines
ax+by=c, slope m1 = -a/b
bx-ay=c, slope m2 = b/a
m1*m2 = (-a/b)(b/a) = -1
Therefore the two lines are perpendicular so the answer is D
See the attached diagram.
In the right triangle, x is opposite the 23.6 degree angle, and the adjacent side is 250 m. This suggests using the tangent ratio.

Finally, to get the height of the tree, add Sarah's height, 1.5 m.
The tree is approximately 110.7m tall.
Answer:
-3
Step-by-step explanation:
2+(-5)
2-5=-3
that is you solve the equation and trace it on the number line
you would divide 1700 by 40
1700/40= 42.5
there for the unit ratio would be 42.5 meters per minute
