Answer:
the first triangle is 10
the second triangle is 8
Step-by-step explanation:
1. the formula for this is a²+b²=c²
c is the missing side
add in the numbers and you get 8²+6²=c²
8² is 64 and 6² is 36. 64+36 = 100
then find the square root of 100, which is 10
2. the formula for this is c²-b²=a²
17² - 15² = a²
289-225 = 64
the square root of 64 is 8
