Answer:

Option D is correct.

Step-by-step explanation:

We are given with a right angled triangle.

Measurement of sides of triangle are a , b , c

and measure of ∠C is 90°

We know that we have a relationship between sides and an angle opposite to a side.

This relation is given by LAW OF COSINES.

In given triangle and using law of cosines, we have

b² = a² + c² - 2ac cos B

a² = b² + c² - 2cb cos A

c² = a² + b² - 2ab cos C  ⇒ c² = a² + b² - 2ab cos(90°)

Therefore, Option D is correct.

Mr. D'Agostino decided he wanted to build a pool in his backyard this summer. He sketched a drawing that had a scale of 1 in. =
Travka [436]

Answer:

46080 ft²

Step-by-step explanation:

Given :

Scale :

1 in = 4 feets

Recall :

I foot =. 12 inches

Length of drawing = 4 feets

Length of drawing in inches = 4 * 12 = 48 inches

Width of drawing = 5 feets

Width of drawing in inches = 5 * 12 = 60 inches

Actual length of pool = 48 * 4 = 192 feets

Actual width of pool = 60 * 4 = 240 feets

The actual area of the pool :

Length * width

192 feets * 240 feets = 46080 ft²

Triangle ABC had a perimeter 18 cm
Alex

Step-by-step explanation:

what is the main condition the lengths of the sides of a right-angled triangle have to fulfill ?

Pythagoras !

c² = a² + b²

c is the Hypotenuse (the baseline opposite of the 90 degree angle), a and b are the so-called legs (the sides enclosing the 90 degree angle).

only if there is a combination of the sides, for which the Pythagoras equation is true, do we have a right-angled triangle. otherwise not.

we also know CA = 18 - 7 - 3 = 8 cm

so, let's try

8² = 7² + 3²

64 = 49 + 9 = 58 wrong

7² = 8² + 3²

49 = 64 + 9 = 73 wrong

3² = 8² + 7²

9 = 64 + 49 = 113 wrong

so, there is no combination, where the Pythagoras equation is true, so it is NOT a right-angled triangle.

If a rectangle is inscribed in a circle, each diagonal also serves another function. What is this function?
Kipish [7]

Answer:

A right triangle inscribed in a circle must have its hypotenuse as the diameter of the circle.

Step-by-step explanation:

A rectangle is made of two right triangles then a rectangle inscribed in a circle must have its diagonal as the diameter of the circle. Hope this helps
