The seats must be arranged in a 38 by 39 arrangement to have the minimum amount of seats used.

Two triangles are similar. The perimeter of the smaller one is 16. The ratio of the corresponding sides is 2:5. The sides of the
Eddi Din [679]

Answer:

Perimeter of larger triangle is 40.

Step-by-step explanation:

Given:

Perimeter of smaller circle = 16

Ratio of corresponding side = 2:5

We need to find the perimeter of the larger triangle.

Solution:

Let the perimeter of the larger triangle be 'x'.

Therefore by theorem which states that;

" When a triangle have scale factor a:b then the ratio of the perimeters is a:b".

Here Ratio is 2:5, so we can say by theorem, Ratio of perimeters is 2:5

framing in equation form we get;

\frac{\textrm{Perimeter of smaller triangle}}{\textrm{Perimeter of Larger triangle}}=\frac{2}{5}

Substituting the values we get;

\frac{16}{x}=\frac{2}{5}

By Cross multiplication we get;

16\times 5=2x\\\\80=2x

Dividing both side by 2 we get;

\frac{80}{2}=\frac{2x}{2}\\\\x=40

Hence Perimeter of larger triangle is 40.

What is x and what's m&lt;M?
sweet [91]

Use the property that angles sum up to 360 degrees.

Also use property that <M = <R and <A = <P.

That gives the following equation:

m<R + m<A + m<M + m<P = 360

6x+5 + 9x+25 + 6x+5 + 9x+25 = 360

30x + 60 = 360

x = 10

Answer:

x = 10

m<M = 6x+5 = 65 degrees
