Diagonal braces were put to hold the formworks, what is the distance of the
braces from the bottom tip to the top tip if it is inclined 35°?

Answer 1

Given :  A 7-meter concrete wall is to be constructed on an erosion prone area.

Diagonal braces were put to hold the formworks,  

To Find : what is the distance of the

braces from the bottom tip to the top tip if it is inclined 35°

Solution:

Height of Wall = 7 m

Angle of inclination  = 35 °  

Sin angle = Height / Hypotenuse

=> Sin  35 °  = Height of Wall / Brace length

=> Sin  35 °  =7 / Brace length

=> Brace length = 12.2 m

Horizontal Distance =    7 / tan35°  = 10  m
