Yes, I will help. What do you need help with?
I'm doing the same thing right now and I'm lost.
You can consider the tree perpendicular to its shadow, therefore you get a triangle rectangle of which you know the two legs and you need to find the angle between the shadow and the hypothenuse, opposite to the tree.
In this case, the angle α can be easily found with trigonometry:
tan α = (opposite side / adjacent side)
Therefore:
α = tan⁻¹ (tree / shadow) = tan⁻¹ (10 / 14) = 35°
NOTE:
tan⁻¹ is sometimes found written as arctan.
A. y=-1.5x+30
B. it's negative because he is using money on the card
C.20, because that is the maximum amount of washes you can get for 30
Value: Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies.
The absolute value of a number is never negative. The absolute value of 5 is 5
