Answer:

Question no 2: shape 1 = 4x180=720 / shape 2= 720/6=120

Step-by-step explanation:

Shape 1 :

The reason we multiply 4 by 180 is because the sum of interior angles of a triangle sum up to 180 and there are 4 triangles so you multiply 4x180 to get 720.

Shape 2 :

In a hexagon all the sides are of the same length (congruent) and all the interior angles are all the same size (congruent) So the find the measure of the interior angles we know that the sum is 720 and there are six angles so... we divide 720/6 which gives us 120

Given the function, f(x)=|x+1|+2, what is the transformation

Vadim26 [7]

Fx=3x
Because f times x equals fx which could be equal to x+1 which is 1x plus 2 which is 3x leaving a product of fx=3x

The sum of 3 times a number and 7, divided by 5, is 17 written as an equation

Anestetic [448]

Equation is: $\frac{3x+7}{5}=15$

and Value of x is $x=68/3\\$

Step-by-step explanation:

We need to write an equation of:

The sum of 3 times a number and 7, divided by 5, is 17

Let the number = x

So, equation will be:

$\frac{3x+7}{5}=15$

We can solve the equation to find the value of x.

$\frac{3x+7}{5}=15\\3x+7=15*5\\3x+7=75\\3x=75-7\\3x=68\\x=68/3\\$

So, Equation is: $\frac{3x+7}{5}=15$

and Value of x is $x=68/3\\$

9. A ladder of length 23 feet leans against the side of a building. The angle of elevation of the ladder is 76. Find the distanc

irakobra [83]

<h3>Answer:</h3>

B) 22.32 feet

$\quad\rule{300pt}{1pt}$

<h3>Solution:</h3>

we are given that , a ladder is placed against a side of building , which forms a right angled triangle . We wre given one side of a right angled triangle ( hypotenuse ) as 23 feet and the angle of elevation as 76 ° . We can find the Perpendicular distance from the top of the ladder go to the ground by using the trigonometric identity:

$\qquad\quad\bull ~{\boxed{\bf{ Sin\theta =\dfrac{Perpendicular}{Hypotenuse}}} }~\bull$
