Please help me with this question it is due today! What value of m makes the system show perpendicular lines? Explain.
Lady bird [3.3K]
M = -2

In perpendicular lines, the slopes are opposite reciprocal. This means you flip the sign (from + to - or from - to +) and flip the numerator and denominator.

So 1/2 becomes negative, and 2/1 = 2

So the slope is -2

Step-by-step explanation:

By finding the missing base side on the original triangle (which is 18), we add 10 to that number to find the base side on the second triangle. We can then use the equation "sin(21.04) = x/30" to find the missing length side (21.04 is the degree measurement).

Hope this helps :)
