Aladder that is 30 ft long needs to reach 27 ft up a building. what should the angle of the vertical be?

64.16^{\circ} or 1.12 radians

Step-by-step explanation:

Given statement : A ladder that is 30 ft long needs to reach 27 ft up a building.

Since, building stands  vertical on the ground , so ladder will make a riaght angle.

So, hypotenuse side = 30 ft.

the side apposite to the angles of the elevation =27 ft

Let x be the angle of elevation.

We know that in a right triangle :-

you have 6 equal triangles, find the area of one of them (b*h/2) and multiply by 6

(8*4: 2)*6 =

32 cm² is your answer
