A triangle has sides with lengths of 60 feet, 63 feet, and 87 feet. Is it a right triangle?
Sedaia [141]

Answer:

Yes

Step-by-step explanation:

We can use the Pythagorean Theorem to check if this triangle is a right triangle:

a^2+b^2=c^2

Note that a and b are the legs of the triangle and c is the hypotenuse:

Substitute the lengths of the sides into the equation:

60^2+63^2=87^2

3600+3969=7569\\7569=7569

Therefore this triangle is a right triangle.

Left parenthesis 5 plus 2 square root of 6 right parenthesis squared = a plus b square root of 6 then the value of a and b are
Ganezh [65]

Answer:

The values of a and b are 33 and \frac{20\sqrt{3}}{3}, respectively.

Step-by-step explanation:

The statement is equivalent to the following mathematic expression:

\left(5 + 2\sqrt{2})^{2} = a + b\cdot \sqrt{6} (1)

By definition of the perfect square trinomial:

25 + 20\cdot \sqrt{2} + 8 = a + b\cdot \sqrt{6}

33 + 20\sqrt{2} = a + b\cdot \sqrt{6}

And by direct comparison we have the following system:

a = 33 (2)

b\cdot \sqrt{6} = 20\sqrt{2} (3)

By (3), we solve for b:

b = \frac{20}{\sqrt{3}}

b = \frac{20\sqrt{3}}{3}

The values of a and b are 33 and \frac{20\sqrt{3}}{3}, respectively.
