5) An airplane approaching a runway needs to know the angle of depression for its approach. Radar at the near end of the runway measures the direct distance to the plane to be 20,000 feet. The pilot looks at the altimeter and sees that
she is currently at an altitude of 5000 feet. What is the arigle of depression of her approach? Draw a picture and
solve with trigonometry.

sorry, i don't know i just need points, i'm new here. chao

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:
