Answer: <ACB = 50 degrees

Step-by-step explanation: Since the interior angles of a triangle is always equal to 180 degrees, you would add both given degrees which is 40 and 90 (because of the right angle) and then subtract that answer (130) from 180

△HFM∼△PST
loris [4]

Answer:

The perimeter of △HFM is 50.75 units

Step-by-step explanation:

<u><em>The correct picture of the question in the attached figure</em></u>

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

we have

△HFM∼△PST ----> given problem

step 1

Find the scale factor

Let

z ----> the scale factor

z=\frac{HF}{PS}

substitute the given values

z=\frac{14}{8}=1.75

step 2

Find the perimeter of triangle PST

Remember that the perimeter of a triangle is the sum of its three length sides

P=8+9+12=29\ units

step 3

Find the perimeter of triangle HFM

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

so

The perimeter of triangle HFM is equal to the perimeter of triangle PST multiplied by the scale factor

so

29(1.75)=50.75\ units

pentagon [3]

To find the answer to a problem like this, we need to look for patterns in the number!

It looks likes x = 2y

Or in other words, (y is being multiplied by 2 to find x!)

**Now that we've discovered this pattern, we can confidently say that ...

<u>the number</u><u> 6</u><u> belongs in</u><u> #1 </u>
