Aladder leans against a building. the foot of the ladder is 2 feet from the building and reaches to a point 7 feet high on the building. what is the measure of the angle formed by the building?

74.05 degree

Step-by-step explanation:

A ladder leans against a building. The foot of the ladder is 2 feet from the building and reaches to a point 7 feet high on the building.

The ladder forms a right angle triangle with the building

Base of the triangle is 2 feet

The distance between the ground and the top of the ladder is 7 feet

the graph is attached below

AB= 2, AC = 7

We know the opposite and the adjacent side so we use tan formula

x = tan^-1 (7/2)

x = 74.05 degree

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
