Answer:
29, height is > 30
Step-by-step explanation:
all the angles in a triangle add up to 180, they give 1 angle 61 degrees and it's a right triangle so 61 + 90 = 151
180 - 151 = 29
the third angle is 29 degrees
The height of the building is found using trigonometry
tangent o/a
tan(61 degrees) = o/30
height = 54.1
height is > 30
