Answer:

12.2 cm

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as obtuse, scalene, equilateral and isosceles triangle. We say that two triangles are similar if the ratio of their corresponding sides are equal and their corresponding angles are also equal.

Since both triangles are similar, then the ratio of their corresponding sides are equal. Hence:

\frac{x}{18} =\frac{17}{25} \\\\x=\frac{17}{25} *18\\\\x=12.2\ cm

How do you find the m and b in the problem y=-x+1?
inysia [295]
In Y=mx+b:

m=slope. That is found by using this formula y2-y1/x2-x1

b=y-intercept. That's found by finding slope, m, and substituting that into y=(m)x+b. Then you have to solve for b and that'll be your y-intercept.

Tamiku [17]

Answer: The lenght of the missing side is 4 cm

Step-by-step explanation:

The correct question is:

<em>The perimeter of the rectangle is 20cm . One side is 6cm. What is the length of the missing side?</em>

So, to answer it we have to apply the next formula:

Perimeter of a rectangle = 2 width + 2 length

Replacing with the values given: (assuming that the side given is the length of the rectangle)

20 = 2(6) + 2x

Solving for x:

20 =12 +2x

20-12 =2x

8 =2x

8/2 =x

4=x

The length of the missing side is 4 cm
