Answer:

The correct option is C. XV is an angle bisector.

Step-by-step explanation:

Altitude: A perpendicular line segment from any vertex of a triangle to the opposite side is called an altitude.

Median: A line segment from any vertex of a triangle to the opposite side, which divides that side is two equal parts is called median.

Angle bisector: A line segment from any vertex of a triangle to the opposite side, which divides the angle of vertex in two equal parts is called an angle bisector.

Perpendicular bisector: A perpendicular line segment from any vertex of a triangle to the opposite side, which divides that side is two equal parts is called perpendicular bisector.

From the given graph it is clear that the line segment XV divides the angle X is two equal parts,

$\angle YXV=\angle ZXV=40^{\circ}$

Therefore, XV is an angle bisector and the correct option is C.

juin [17]

The number of cherries left is 26

Ely has 54 strawberries now

Solution:

Given that, Ely has a bag of 42 strawberries. She eats 16 strawberries

To find: Number of cherries left

From given,

Total number of strawberries = 42

Number of strawberries eaten = 16

Therefore,

Number of cherries left = Total number of strawberries - Number of strawberries eaten

Number of cherries left = 42 - 16 = 26

Thus, number of cherries left is 26

The next day she goes to the store and buys 28 more cherries

Number of cherries bought = 28

Therefore,

Total number of cherries she has now = number of cherries left + Number of cherries bought

Total number of cherries she has now = 26 + 28 = 54

Thus she has 54 strawberries now

Nastasia [14]

Answer:

$\frac{1}{2}$

Step-by-step explanation:

sin( $cos^{-1}$ $\frac{\sqrt{3} }{2}$ )

using the sides of the 30- 60- 90 triangle

with legs 1, $\sqrt{3}$ and hypotenuse 2 , then

$cos^{-1}$ $\frac{\sqrt{3} }{2}$ = 30° and

sin30° = $\frac{1}{2}$

Lina20 [59]

Since 500 is the area, and 20 is the length, divide 500 by 20. Your answer is a decimal. (0.04) therefore, you have to make it into a whole number. So move the decimal to the right two times. So 4 is your height.

Which answer includes the intrevals that contain the solution to the inequality x^2-1/3x+9<0

victus00 [196]

Answer:

x<±1 and x< -3

Step-by-step explanation:

Given the inequality x^2-1/3x+9<0, we are to find the values of x that satisfies the inequality

x^2-1/3x+9<0

x^2-1/3x+9 (3x+9)²<0* (3x+9)²

(x^2-1)(3x+9) < 0

x²-1 < 0 and 3x + 9 <0

x²-1 < 0

x²<1

x<±√1

x<±1

Also 3x + 9 <0

3x < -9

x < -9/3

x < -3

Hence the required values of x are x<±1 and x< -3
