Answer:

It is not a right angled troagle

Step-by-step explanation:

Given

Sides: 5m, 7m and 9m

Required

Is it a right angled triangle?

A triangle is right angled if:

$a^2 = b^2 + c^2$

Where a is the longest side and b,c is any of the other.

So, we have:

$9^2 = 5^2 + 7^2$

$81 = 25 + 49$

$81 \neq 74$

Since they're not equal then it is not a right angled troagle

Figure AAA is a scale image of Figure BBB. What is the value of xxx?

Arada [10]

Answer:

The scale factor from Figure A to Figure B is 1/2

Step-by-step explanation:

The correct question is

Figure B is a scaled copy of Figure A.

What is the scale factor from Figure A to Figure B?

The picture in the attached figure

we know that

A dilation is a non rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional

In this problem Figure A and Figure B are similar

To find out the scale factor, determine the ratio of its vertical corresponding sides

The vertical side of figure A is 4 units

The corresponding side in figure B is 2 units

$\frac{2}{4}=\frac{1}{2}$

The scale factor is less than 1

The dilation is a reduction

therefore

The scale factor from Figure A to Figure B is 1/2
