Question

A Triangle has a leg that measures 3 and a hypotenuse of 9. Which leg measure would form a right triangle?

A)12
B)90
C)✔️72
D)✔️90

Answer 1

`3² + b² = c² `

Answer 2

Solve for b (only take the positive value of the square root that you get)

Answer 3

I meant `3² + b² = 9² `

Answer 4

This will take another shape, (rearrangement)

b=√(3²+9²)=√(9+81)=√90=√(9 × 10)= 3√10 ≈ 9.487
