The area of right triangle QRS will be;

⇒ The area of triangle = 20

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

In ΔQRS;

Base = x

Height = 2x

Hypotenuse = 10

Now,

Since, The triangle is a right triangle.

Hence, The triangle QRS satisfy the condition of Pythagoras theorem.

So, We get;

⇒ Hypotenuse² = Base² + Height²

⇒ 10² = x² + (2x)²

⇒ 100 = x² + 4x²

⇒ 100 = 5x²

⇒ x² = 20

⇒ x = √20

So, The Height of triangle = 2√20

And, The Base of the triangle = √20

We know that;

⇒ The area of triangle = 1/2 × Height × Base

⇒ The area of triangle = 1/2 × 2√20 × √20

⇒ The area of triangle = 20

Thus, The area of right triangle QRS = 20

Answer:

3:5

Step-by-step explanation:

The simplest ratio of circles to squares is 3/5.

Here,

Given that there are 15 squares and 9 circles.

We have to find, the simplest ratio of circles to squares.

What is Simplest ratio?

A ratio is said to be is the simplest form or in the lowest term if two quantities of a ratio have no common factor other than 1.

Now,

There are 15 squares and 9 circles.

Hence,  the simplest ratio of circles to squares = [tex]\frac{9}{15}[/tex]

                                                                        = [tex]\frac{3}{5}[/tex]

So, The simplest ratio of circles to squares is 3/5.

Answer:

60.

Step-by-step explanation:

I can't see the question above this and what information it gives, but If I'm not mistaken, that shape is a rectangle, so regardless of whether there's a piece of the last side missing, the sides across from each other are congruent in size.

So if the top is 14, then the bottom is 14, and since the left side is 16, then the side missing a piece adds up to 16.

(14*2) + (16*2) =

28 + 32 = 60.

Answer:

We have 6 flamy and 10 Elephants

Step-by-step explanation:

A local zoo has flamingos and elephants in one exhibit.

Flamingos have 2 legs

Elephants have 4 legs

Let the number of

Flamingos = x

Elephants = y

There are 16 animals in the exhibit

= x + y = 16..... Equation 1

x = 16 - y

The animals have a risk of 52 legs.

2 × x + 4 × y = 52

2x + 4y = 52..... Equation 2

We substitute 16 - y for x in Equation 2

2(16 - y) + 4y = 52

32 - 2y + 4y = 52

- 2y + 4y = 52 - 32

2y = 20

y = 20/2

y = 10

Solving for x

x = 16 - y

x = 16 - 10

x = 6

Hence, we have

Flamingos = x = 6 flamingos

Elephants = y = 10 Elephants
