Find the length of the unknown side. *
the numbers on the triangle are 15,17 and A
2 m
4 m
8 m
16 m
If it's a rightangled triangle ...
A^2 = 17^2 - 15^2
Otherwise, not enough data
is this sign ^ mean divide or mulitiply
To find the length of the unknown side in this triangle, we can use the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
In this case, we have the numbers 15, 17, and A as the lengths of the sides. We can plug in the known values into the theorem and solve for A.
Let's label the sides as follows:
A: Unknown side
15: One known side
17: The hypotenuse
Using the formula, it becomes:
A^2 + 15^2 = 17^2
Simplifying:
A^2 + 225 = 289
Now, let's solve for A:
A^2 = 289 - 225
A^2 = 64
To get the length of A, we need to take the square root of both sides:
A = √64
A = 8
Therefore, the length of the unknown side (A) is 8 units.
