The slope of perpendicular lines should always be the reciprocal.
Thus, the slope of a line perpendicular should be -6/1x.
First of all, just to avoid being snookered by a trick question, we should verify that these are really right triangles:
7² + 24² really is 25² , and 8² + 15² really is 17² , so we're OK there.
In the first one:
sin(one acute angle) = 7/25 = 0.28
the angle = sin⁻¹ (0.28) = 16.26°
the other acute angle = (90° - 16.26°) = 73.74°
In the second one:
sin(one acute angle) = 8/17 = 0.4706...
the angle = sin⁻¹ (0.4706...) = 28.07°
the other acute angle = (90° - 28.07°) = 61.93°
I'm sorry, but just now, I don't know how to do the
third triangle in the question.
Answer:
Step-by-step explanation:
Let it be x.
<u>Then we have:</u>
- 50 = 1/3x
- x = 50*3
- x = 150 min = 2.5 hr
