Math Problem Statement

if it is known that a is 2 and b is 2 the square root of 3 then the result is (squared root)....... (using Pythagoras)

Solution

Given that a=2a = 2 and b=23b = 2\sqrt{3}, we can use the Pythagorean theorem to find the length of the hypotenuse cc of a right triangle with sides aa and bb.

The Pythagorean theorem states:

c=a2+b2c = \sqrt{a^2 + b^2}

Substituting the values of aa and bb into the formula:

c=22+(23)2c = \sqrt{2^2 + (2\sqrt{3})^2}

Now, calculate each term inside the square root:

  1. 22=42^2 = 4
  2. (23)2=22(3)2=43=12(2\sqrt{3})^2 = 2^2 \cdot (\sqrt{3})^2 = 4 \cdot 3 = 12

Add these results together:

c=4+12c = \sqrt{4 + 12}

c=16c = \sqrt{16}

Since 16=4\sqrt{16} = 4, the length of the hypotenuse cc is 44.

Summary

Given a=2a = 2 and b=23b = 2\sqrt{3}, using the Pythagorean theorem, the hypotenuse cc is 44.
