So you would add lmu and umn together to equal lmn. My notes are in the picture but the answer is umn=42 and x=1
Answer:
x=64
Step-by-step explanation:
Both the semicircle that says 180, and the right angle sign in the image serve to support the idea that all parts of the figure equal 90
Therefore, it is safe to say that you need to subtract 26 from 90 in order to solve for x.
90-26 = 64
There are no numbers with an A between 1-100
Perpendicular means that it has a slope that is the reciprocal of the original, and parallel means that the slopes are the same.
