Which equation can be used to find the unknown length, a, in this triangle?
A right triangle has a side with length 15 meters and hypotenuse with length 17 meters. The other side is labeled a.
A. a squared + 15 squared = 17 squared
B. 15 squared + 17 squared = a squared
C. a squared + 15 = 17 squared
D. a + 15 squared = 17 squared
Answer:
The equation is used to find the unknown length (a) will be 17² =15² + a². Then the correct option is A.
What is a Pythagoras theorem?
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
A right triangle has a side with length 15 meters and a hypotenuse with length 17 meters.
The other side is labeled a.
17² =15² + a²
Then the correct option is A.
