Answer:
3, 14, and sqrt205.
2,9, and sqrt85.
Step-by-step explanation:
Check if they fit the Pythagoras theorem c^2 = a^2 + b^2:
3^2 = 9 , 14^2 = 196.
9 + 196 = 205 which is the square of sqrt205.
So this is a right angled triangle.
6^2 + 11^2 = 36 + 121
= 157 Not right-angled.
19^2 + 180^2 = 32761 Not right-angled.
3^2 + 19^2 = 370 Not right-angled.
2^2 + 9^2 = 85, So this is right angled..

Answer:
true
Step-by-step explanation:
1/2 (sin(x+y)+sin(x-y))
= 1/2 (sin x cos Y + cos x sin y + sin x cos y - cos x sin y)
= 1/2 * 2 sin x cos y
= sin x cos y
The expression is true.
