Answer:
45 degrees
Step-by-step explanation:
A straight line is an angle with a measure of 180°, but becasue it looks like we have two angles that create the 180° angle, therefore, it is a supplementary angle.
Knowing this
2X = 90° (right angle)
so (2X) + (2X) = 180° (supplementary angle)
Therefore, to find X you can do
2X = 90
divide by 2 on both sides (to isolate the variable we are trying to find which is X)
and you get....
X= 45 becasue 2 times 45 equals 90
answer: X=45°
Sample space of two fair 6 sided dice is 36.
Product = perfect square are (1, 1), (1, 4), (2, 2), (3, 3), (4, 4), (5, 5), (6, 6)
Probability that their product is perfect square = 7/36
