Suppose a 15-foot ladder is leaning against a building, reaching to the bottom of a second-floor window 11 feet above the ground. What angle, in radians, does the ladder make with the building? (Round your answer to two decimal places.)

Angle in radian = 0.75

Step-by-step explanation:

Given:

Height  = 11 ft

Hypotenuse = 15 ft

Find:

Angle in radian

Computation:

Cosθ = Height / Hypotenuse

Cosθ =  11/ 15

Angle in radian = 0.75

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
