For this question, we are going to use right triangle trig and possibly law of signs to find the height of the tree, not the one that i have labeled.
00:13
We want to find the height of the tree.
00:22
All right.
00:23
We have two right triangles.
00:27
Let's start with the large right triangle and find this value using right triangle trig.
00:40
The sign of 53 degrees is opposite over hypotenuse.
00:50
Multiply both sides by 235 and 235 sign of 53 is 187 .68 feet.
01:11
We could also find, using pythagorean theorem or right triangle trig, the length of the other leg of the triangle.
01:29
To do that, we would use cosine.
01:34
I'll call that b for base, maybe.
01:38
And the cosine of 53 degrees is equal to the base over the hypotenuse, the adjacent over the hypotenuse, multiply both sides by 2 .35...
