Answer:

A is the answer

Step-by-step explanation:

we can eliminate D as the answer because an equilateral triangle has sides that are all the same length

we can see if it's a right triangle by using the Pythagorean Theorem which says the sum of the square of the legs is equal to the square of the hypotenuse (which is the longest side)

does 5² + 7² = 10²?

no, 25 + 49 ≠ 100

so, we can eliminate B as the answer

we can eliminate C because an isosceles triangle has two sides which have the same length

therefore, the answer is A, a scalene triangle which has three unique side lengths
