Answer:
sin© = 3/5
Cos© = 4/5
Tan© = 3/4
Explanation:
The opposite (opp) side of the right angle triangle is the side facing the angle ©
The hypothenus (hyp) side is the longest side,
The adjacent (adj) side is the third side.
sin© = opp/hyp
Cos© = adj/hyp
Tan© = opp/adj
Answer:
- Yes it is a right triangle
- The side lengths satisfy the Pythagorean theorem equation
Step-by-step explanation:
We can test these numbers to see if they satisfy the Pythagorean theorem equation:
15² = 9² + 12²
225 = 81 + 144 . . . . true
Since the numbers satisy the Pythagorean theorem relation, they belong to a right triangle.
____
You can recognize that the ratio of side lengths is ...
9 : 12 : 15 = 3 : 4 : 5
Further, you can recognize that the side lengths 3, 4, 5 belong to the right triangle with the smallest integer side lengths that satisfy the Pythagorean theorem. Hence the 9 : 12 : 15 triangle is similar (by a scale factor of 3) to a right triangle, thus is a right triangle.
