Solve triangles: angle bisector theorem

Mathematics
1 answer:
Readme [11.4K]3 years ago
8 0

Answer:

Step-by-step explanation:

CD/6.5 = 2.6/4.9    This is the result of the angle bisector theorem.

The theorem basically says that the side opposite the angle being bisected is divided  the ratio of the sides enclosing the angle.

Multiply both sides of the proportion by 6.5

CD = 2.6 * 6.5 / 4.9

CD = 3.4489

CD = 3.4 rounded.

Marcus rented a movie 4 dollars and some video games 6 dollars each he paid 22 dollars how many games did he rent ?
Margaret [11]

Answer:

Marcus rented 3 video games.

Step-by-step explanation:

Let "x" be the number of games he rented.

The equation is 4 + 6x = 22

Solve the equation.

4 + 6x = 22

Subtract 4 from both sides of the equation.

6x = 18

Divide both sides by 6.

x = 3

Marcus rented 3 video games.

Hope you will understand the concept.

Thank you.

Use the table to work out the values of a , b , c , and d .​
rodikova [14]

Answer:

a = 16, b = 6, c = - 4, d = - 9

Step-by-step explanation:

Substitute the appropriate values of x into the equation and evaluate.

x = - 3 : y = 1 - 5(- 3) = 1 + 15 = 16 → a

x = - 1 : y = 1 - 5(- 1) = 1 + 5 = 6 → b

x = 1 : y = 1 - 5(1) = 1 - 5 = - 4 → c

x = 2 : y = 1 - 5(2) = 1 - 10 = - 9 → d

PLEASE SOLVE QUICKLY I WILL MAKE YOU BRAINLIEST!!!
Solnce55 [7]

Answer:

x=25°, y=18°

Step-by-step explanation:

Solved! Here is the explanation. As we have supplementary angles, we have a total of 180° of angles. Angle BXD is a right angle, so 2x+40°=90°. 2x=50°, and then we have x=25°. Now, to figure out y, we have to look at angle BXA. In this case, 5y=90°. y=18°. So, x=25° and y=18°. Hope this explanation helps!

A cone with volume 2880 m³ is dilated by a scale factor of 1/4. What is the volume of the resulting cone?
labwork [276]
The volume of the cone is 2880 m3.
The scale factor is 1/4.
The volume of the cone has the formula (1/3)π r² h.
A scale factor of 1/4 will reduce the dimensions by 1/4 which will result to a total volume reduction of (1/4)³ = 1/64
The new volume will be 45 m3

Write a equation in slope intersect form for points (0,8) and (9,5)
lyudmila [28]

y = mx+b

(5-8)/(9-0) = -1/3 which is m

solve point slope to find slope intercept by using one of the points (0,8)

y-y1=m(x-x1)

y-8 = -1/3(x-0)

y-8 = -1/3x

Answer: y = -1/3x + 8
