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
