Answer 1

Answer:

Answer:

75 ft

Step-by-step explanation:

Here we are given a right angled triangle with a known angle of 20°, length of the hypotenuse to be 80 and we are to find the length of the base x.

For that, we can use the formula for cosine for which we need an angle and the lengths of base and hypotenuse.

$cos \alpha =(base)/(hypotenuse)$

So putting in the given values to get:

$cos 20=(x)/(80) \n\nx= cos 20*80\n\nx=75.17$

Therefore, the value of x is the closest to 75 ft.

1 Which expression is equivalent to 1/3y?• 1/3(y+12)-12
1/6y+1/3(y+3
1/6y+1/6(y+12)-2
1/3y+1/3(6-y)

Answers

Answer:

1/6y+1/6(y+12)- 2

Step-by-step explanation:

Distribute $(1)/(6)$ through the parentheses : $(1)/(6)$ y + $(1)/(6)$ y + 2 - 2

Remove the opposites and calculate ( since two opposites add up to zero remove them from the expression) : $(1)/(6)$ y + $(1)/(6)$ y

Calculate the sum : $(1)/(3)$ y

Solution : $(1)/(3)$ y

Answer:

The answer is 1/6y+1/6(y+12)-2

Find the area of the figure to the nearest square unit.

Answers

Answer:

357 mi²

Step-by-step explanation:

The shape is made of a triangle and a half-square

we will calculate the area of each one

The half square:

let A1 be the area of the half-circle:

A1= (10²*π)/2 = 50π mi²

The rectangle:

Let A2 be the area of the triangle:

A2= 10*20=200 mi²

The whole shape:

let At be the total area:

At =A1+A2= 200+50π =357.07≈ 357 mi²
