Atriangular sail has a diagonal length of 53 feet and a width of 45 feet. the height of the sail in feet’s is h. which equation can be used to find the value of h?

We can use the Pythogoras theorem:

Step-by-step explanation:

It is given that the diagonal length of the triangular sail is 53 feet.

It is also given that the width of the triangular sail is 45 feet.

The height of the triangular sail is h feet.

From the figure, we observe that the triangle is right angled.

So, we can use the Pythogoras theorem to determine the height h.

From the Pythogoras theorem,

Or,

= (53+45) (53-45)

= 98 × 8

= 2 × 49 × 8

= 16 × 49

h = 4 × 7

= 28 feet

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.
