CAYB is a quadrilateral

X is the point on AB such that AX:XB= 1:2

Prove that CX = 2/5 CY

Answers

Answer:

see explanation

Step-by-step explanation:

CY = CB + BY

     = 6b + 5a - b

     = 5a + 5b

---------------------

CX = CA + AX

     = CA + [tex]\frac{1}{3}[/tex] AB , find AB

AB = AC + CB

     = - 3a + 6b

     = 6b - 3a

Thus

CX = CA  + [tex]\frac{1}{3}[/tex] AB

      = 3a + [tex]\frac{1}{3}[/tex](6b - 3a)

      = 3a + 2b - a

      = 2a + 2b

---------------------

and

[tex]\frac{2}{5}[/tex] CY

= [tex]\frac{2}{5}[/tex] (5a + 5b)

= 2a + 2b = CX

Hence CX = [tex]\frac{2}{5}[/tex] CY ⇒ Proven

Answers

Answer:

y=90⁰

Step-by-step explanation:

● 180⁰-110⁰=70⁰ (lines on a straight line)

70⁰+70⁰+x+x= 180⁰( sum of a triangle=180⁰)

2x=40⁰

x=20⁰

● 70⁰+20⁰+y=180⁰(sum of a triangle =180⁰)

y=180⁰-90⁰

y=90⁰

Angles of the triangle:

angle1 = 70°

angle2 = (x + x)°

angle3 = (180 - 110)°

By angle sum property of a triangle,

angle1 + angle2 + angle3 = 180°

Therefore,

70 + (x + x) + (180 - 110) = 180

70 + 2x + 70 = 180

140 + 2x = 180

2x = 180 - 140

2x = 40

x = 40/2

x = 20

Hence, x = 20°

It takes 10 pounds of potatoes to make 15 pounds of mashed potatoes. At this rate: How many pounds of potatoes are needed to make 50 pounds of mashed potatoes?

Answers

Answer:

Step-by-step explanation:

You need to set up a proportion.

10 pounds of potatoes/15 pounds of mashed potatoes

Before going on notice that the potatoes are on the top part of the fraction and the mashed potatoes are on the bottom. The right hand side of the proportion must be the same.

10 pounds potatoes/15 pounds mashed = x pounds / 50 pounds mashed.

The raw potatoes are on the top, The mashed is on the bottom. It's always like that.

The second step is to cross multiply.

10 / 15 = x / 50          Cross miultiply

10*50 = 15 * x            Combine the left

500 = 15x                  Divide by 15

500/15 = x

x = 33.33

, find the length of QS and TV.

Answers

The length of the segment QS is 8 units and the length of the segment TV is 8 units and this can be determined by using similar triangle properties.

Given :

Triangle QRS is congruent to triangle TUV.The length of the segment QS is (3v + 2).The length of the segment TV is (7v - 6).

The following steps can be used in order to determine the length of QS and TV:

Step 1 - According to the given data, the triangle QRS is congruent to triangle TUV.

Step 2 - So, the length of the segment QS is equal to the length of the segment TV.

QS = TV

Step 3 - Substitute the values of QS and TV in the above expression.

3v + 2 = 7v - 6

7v - 3v = 6 + 2

4v = 8

v = 2

Step 4 - The length of the segment QS and TV is:

QS = 3(2) + 2 = 6 + 2

QS = 8

TV = 7(2) - 6 = 14 - 6

TV = 8
