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.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
