Pythagorean theorem, a^2 + b^2 = c^2
5 squared is 25, 8 squared is 64, square root of 89 is 9.43 thus the hypotenuse is 9.43, correct me if I'm wrong but that is what I got

Answer:

The value of x is \sqrt{89}

Step-by-step explanation:

 Given : A right angled triangle with base = 8 , perpendicular = 5

We have to find the value of  x that is we have to find the length of hypotenuse.

Consider the given right angled triangle,

PYTHAGORAS THEOREM states that for a given right angle triangle the  sum of square of base and perpendicular is equal to the square of hypotenuse.

Mathematically written as ,

H^2=B^2+P^2

Here, B = 8 , P = 5

substitute, we have,

H^2=8^2+5^2

Simplify, we have,

H^2=64+25

H^2=89

Taking square root both side, we have,

H=\sqrt{89}

Thus, The value of x is \sqrt{89}

astra-53 [7]

Answer:

Step-by-step explanation:

We are given a circle with a partially shaded region. First, we need to determine the area of the whole circle. To do this, we need the measurement of the radius of the circle:

Use the Pythagorean theorem to solve for the other leg of the right triangle inside the circle:

5^2 = 3^2 + x^2

x = 4

The radius is 4 + 1 cm = 5 cm

So the area of the circle is A = pi*r^2

A = 3.14 * (5)^2  

A = 25pi cm^2

To solve for the area of the shaded region:

Ashaded = Acircle - Atriangles

we need to solve for the area of the triangles:

A = 1/2 *b*h

A = 1/2 *6 * 5

A = 15 cm^2

Atriangles = 2 * 15  

Atriangles = 30 cm^2

Ashaded = 25pi - 30
