You take 90 + 75 = 165 and then 180 - 165 = 15 degrees so that’s your answer
An equilateral triangle is a triangle where all sides are of equal lengths. So, the angles are of equal values as well which is 60. We use the angle and the height of the triangle to determine the side length. We do as follows:
tan (60) = 15 / base/2
base = 10√3 = side length
n - 8 < -8
< is similar to = in this case
n < -8 + 8
n < 3
The answer would be bubble #3.
