Which postulate or theorem establishes that the triangles are similar?

Answers

Answer 1

Answer:

AA similarity

Step-by-step explanation:

Your question is not well presented.

See attachment

Given

Triangles ABC and DBE

Required

Which postulate supports the similarities of ABC and DBE

At the first transformation (180 degrees rotation) both triangles maintain SSS and AAA relationships. i.e Side-Side-Side and Angle-Angle-Angle

This is so because rotations do not alter the side lengths; neither does it alter the angles.

When the second transformation (dilation) takes place, the lengths of both triangles ABC and DBE become different because dilation alters side lengths.

However, angle measurements remain unaltered.

Hence, AAA similarity answers the question

5(-1x+5)=10 pls help

Answers

Answer:

-5x+5=10

-5x=10-5

-5x=5

x=-5/5

x=-1

Answer: x = 3

Step by step

5 ( –1x + 5) = 10

(1) Distribute

= – 5x + 25 = 10

(2) Subtract 25 from both sides of the equation

= –5x + 25 -25 = 10 – 25

(3) Simplify

= –5x = – 15

(4) Divide both sides of the equation by the same factor

= –5x/–5 = –15/ –5

(5) Divide the number

= x = –15/–5

Answer: x = 3

Lines N and Pare parallel. Angle M measures 126 degrees. Find the measure of angle Q.

Answers

Answer:

Q= 126°

Step-by-step explanation:

Using the picture given, because these are parallel lines broken by a transversal, we can say the following

M=A=Q=F

B=C=D=G

Since, for example, M and C are the same line, we can say that M+C=180 and so on.

M=Q

Q= 126°

kiersten is 6ft tall. She is standing in front of a tree and notices her shadow. If her shadow is 9 feet away from her and the shadow of the tree is 84 feet away from the tree, how tall is the tree?

Answers

If kiersten is 6ft tall. She is standing in front of a tree and notices her shadow and her shadow is 9 feet away from her. The height of the tree is 56 feet.

How to find the height?

Given data:

kiersten height = 6ft tall

Shadow = 9 feet away

Shadow of tree = 84 feet

The equation that will be use to find the height is 6/9= x/84

Let x represent the tree's height

So, let solve for x

6/9= x/84

Cross multiply:

9x = 6(84)

9x = 504

Divide both side by 9x

x= 504/9

x = 56 feet

Therefore we can conclude that the height of the tree is 56 feet.

The two circles have different diameters in the ratio 5:3.
(A) Calculate the radius of circle B if circle A has a radius of 35mm

(B) Calculate the area of circle A giving your answer to the nearest cm squared.

Answers

Answer:

a) 21 mm

b) 39 cm^2

Step-by-step explanation:

a) The ratio of the diameter from A to B is 5:3

Let the diameter of B be x

If 35 is the radius of A, then its diameter is 35 * 2 = 70 mm

Thus;

5/3 = 70/x

5* x = 70 * 3

5x = 210

x = 210/5

x = 42 mm

So the radius of circle B will be 42/2 = 21 mm

b) The area of circle A

Mathematically we apply the area of a circle formula here

A = pi * r^2

A = 22/7 * 35 * 35

A = 3,850 mm^2

To convert this to cm^2, we will

need to divide by 100

That would be 3850/100 = 38.5 cm^2 = 39 cm^2

pedro placed an order with an online nursery for 6 apple trees and 5 azaleas and the order came to $219. the next order for 3 apple tree and 4 azaleas came to $132. what was the unit cost for each apple tree and for each azalea?

Answers

X = apples trees
Y= azaleas


6x + 5y = 219
3x + 4y = 132

-2(3x + 4y = 132)
-6x - 8y = -264
6x + 5y = 219
-3y = -45
-3y/-3 = -45/-3
y = 15

6x + 5y = 219
6x + 5(15) = 219
6x + 75 - 75 = 219 - 75
6x/6 = 144/6
X = 24

The cost for each apple tree is $24 and fit each azalea is $15

The cost for each apple tree is; $24 and fit each azalea would be; $15.

What is a system of equations?

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Let consider X = apples trees and Y= azaleas

Therefore, the system of equation is;

6x + 5y = 219

3x + 4y = 132

Solving;

-2(3x + 4y = 132)

-6x - 8y = -264

6x + 5y = 219

-3y = -45

-3y/-3 = -45/-3

y = 15

Now substitute;

6x + 5y = 219

6x + 5(15) = 219

6x + 75 - 75 = 219 - 75

6x/6 = 144/6

X = 24

Thus, The cost for each apple tree is; $24 and fit each azalea would be; $15.
