Answer: Option 'a' is correct.

Step-by-step explanation:

Since we know that

Obtuse angles are those angles which is lies between 90° and 180°.

And the bisector of an obtuse angle forms acute angles because of the definition of an obtuse angle, their bisectors form acute angle.

As we know that the bisectors divides the angle (here, obtuse angle) into two equal and smaller parts.

So, anyhow, it can be acute angles.

Hence, Option 'a' is correct.

You have 42 ft. of fencing (1 ft. segments) to make a rectangular garden. How much should each side be to maximize your total ar

Verizon [17]

Answer:

$Length=10.5\ ft$

$Width=10.5\ ft$

$Area=110.25\ ft^{2}$

Step-by-step explanation:

Let

x----> the length of the rectangular garden

y---> the width of the rectangular garden

we know that

The perimeter of the rectangle is equal to

$P=2(x+y)$

we have

$P=42\ ft$

$42=2(x+y)$

simplify

$21=(x+y)$

$y=21-x$ ------> equation A

Remember that the area of rectangle is equal to

$A=xy$ ----> equation B

substitute equation A in equation B

$A=x(21-x)$

$A=21x-x^{2}$ ----> this is a vertical parabola open downward

The vertex is a maximum

The y-coordinate of the vertex is the maximum area

The x-coordinate of the vertex is the length side of the rectangle that maximize the area

using a graphing tool

The vertex is the point $(10.5,110.25)$

see the attached figure

$x=10.5\ ft$

Find the value of y

$y=21-10.5=10.5\ ft$

The garden is a square

the area is equal to

$A=(10.5)(10.5)=110.25\ ft^{2}$ ----> is equal to the y-coordinate of the vertex is correct

What is the solution for 2x -4= -8

scoray [572]

Answer:

x = 48

Step-by-step explanation:

3x + 9 = 153

subtract 9 from both sides -9 -9

3x = 144

divide both sides by 3 3x/3 = 144/3

2x + (x + 9) = 153

2(48) + (48 + 9) = 153

96 + 57 = 153

153 = 153
