Answer:
Measure of side b = 15.
Explanation:
Given that a triangle ABC, whose one angle is 90 degree.
∠C = 90
In triangle ΔABC,
a, b, c are opposite sides of ∠A, ∠B, ∠C respectively.
a = 8 (leg)
c = 17 (hypotenuse longest side)
b = ?
According to Pythagoras theorem,
a² + b² = c²
8² + b² = 17²
64 + b² = 289
b² = 289 - 64
b² = 225
take square root both the side.
b = √225
b = 15.
So, Measure of side b = 15
That's the final answer.
