A18 foot ladder is used to scale a wall. the angle of elevation from the ground is 60 degrees how far is the bottom of the
ladder from the base of the wall?

Answer

9ft from the wall

Explanation

Information given:

Hypothenuse (or ladder): 18ft

Angle of elevation: 60 degrees

Use 60-30-90 to solve for the answer

2x = 18

x = 9

The bottom of the ladder is 9ft from the wall.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
