Answer:
Yes
Step-by-step explanation:
We can use the Pythagorean Theorem to check if this triangle is a right triangle:
[tex]a^2+b^2=c^2[/tex]
Note that [tex]a[/tex] and [tex]b[/tex] are the legs of the triangle and [tex]c[/tex] is the hypotenuse:
Substitute the lengths of the sides into the equation:
[tex]60^2+63^2=87^2[/tex]
[tex]3600+3969=7569\\7569=7569[/tex]
Therefore this triangle is a right triangle.
