Answer:
See the explanation.
Step-by-step explanation:
The Pythagorean theorem states that a^2 + b^2 = c^2, where a and b are the legs of the triangle and c is the hypotenuse (diagonal, longest side) of the triangle.
We can see that the legs are labeled 15 (blue) and 8 (red). Substitute that into the equation.
(8)^2 + (15) ^2 = c^2
From there, we can simplify and solve for c.
64 + 225 = c^2. Add.
289 = c^2. Take the square root.
c = 17.
I hope this helps!
Answer: 17
Pro tip: 3/4/5, 5/12/13 and 8/15/17 are the first three Pythagorean Triples on the list and teachers like to use them for problems. The multiples also come up, like 6/8/10. Learn these and save yourself some calculation down the road.
Let's do it like they want
a² + b² = c²
8² + 15² = c²
64 + 225 = c²
289 = c²
√289 = √c²
17 = c
