Answer:
1. Since the angles on the both sides are the same
5x = 100
x = 20
The mistake is that it is absolutely unnecessary to use 180.
2. It is a right angle, which means it would be 90 degrees instead of 180.
3x + 39 = 90
3x + 39 - 39 = 90 - 39
3x = 51
3x = 17
3. The process is wrong
It should be
6x + 2x + 8 = 180
8x + 8 = 180
8x = 172
x = 21.5
Answer:
I agree that this question can be confusing:
Apparently point A and point B must be on the same straight line (measured from the light house or the question would be nonsensical)
tan 13 = H / DA where H is height of lighthouse
tan 8 = H / DB tangent measured from point B
tan 13 / tan 8 = DB / DA
DB = .2309 / .1405 * 1279 = 2101 ft
DB - DA = 2101 - 1279 = 822.0 ft
they are parallel, so they have the same slope. subtract y2 from y1 (7-1) and divide it by x2-x1 (4-1). you get 6/3, which is 2
