Find the perimeter of the right triangle.
2 answers:
Answer:
b. 36
Step-by-step explanation:
You have to use Pythagorean theorem. A squared + b squared = c squared.
a=12 12^2 (12 squared)= 144
b=9 9^2 (9 squared)= 81
144+81=225
Then you find the square root of 225 which is 15. Since you have the length for side c.
12+9+15=36
Answer:
Step-by-step explanation
You would first have to find the hypotenuse to do that you would follow the formula c = √a²+b², giving you 15.
Next you would add all the sides P = a+b+c, giving you 36.
The perimeter of this triangle would be 36.
