A10-foot board rest against a wall. the angle that the board makes with the ground is 60 degrees. how far is the base of the board away from the wall? select the correct trig ratio and distance from wall?

The base of the board away from the wall is 5 foot .

Step-by-step explanation:

As given

A 10-foot board rest against a wall. the angle that the board makes with the ground is 60 degrees.

Now by using the trigonometric identity.

As shown in the figure given below.

Base = CB

Hypotenuse = AC = 10 foot

Put in the identity

Put in the above

BC = 10 × 0.5

BC = 5 foot

Therefore the base of the board away from the wall is 5 foot .

answer: check all that apply, where the options?

step-by-step explanation:

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
