Answer:
k = 30
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an exterior angle of the triangle, thus
k + 90 = 120 ( subtract 90 from both sides )
30
Well we know the first angle is 90 degrees, which means we have 90 degrees left to work with. Then, the top angle would be 60 degrees, because there is a straight line (which of course has to equal 180), so 180-120 = 60. Now, 90-60=30!
False, 5 is not a factor of 54.
Answer:8
yes that is correct. Do you have a question about it?
