A12-foot board rests against a wall. the angle that the board makes with the ground is 60. how far is the base of the board away from the wall?

ground = 6.928 ft

Step-by-step explanation:

tan 60 = opposite/ adjacent

tan 60 =12/ ground

multiply by ground

ground * tan 60 = 12

divide by tan 60

ground = 12/tan 60

ground = 6.928 ft

6 foot away

Step-by-step explanation:

A board AC with measure of 12 foot rests against the wall.

The angle that board makes with the ground is 60°

Then we have to calculate the distance ( BC) of board from the wall.

Cos 60° =

=  

BC =  

     = 6 foot

Therefore, board is 6 foot away from the wall.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

irrational, cannot
