Answer:
B 41.4
Step-by-step explanation:
complete Pythagoras for general triangles :
c² = a² + b² - 2ab×cos(C)
with "c" being the side opposite of the angle C.
=>
8² = 10² + 12² - 2×10×12×cos(C)
64 = 244 - 240×cos(C)
240×cos(C) = 244 - 64 = 180
cos(C) = 180/240 = 18/24 = 3/4 = 0.75
C = 41.40962211... ≈ 41.4

Answer:
7/60
Step-by-step explanation:
U find the common denominator, subtract how you would with negative and postive integers, and check if you can simplify
Answer:
1 no
2yes
3 no
4 no
5 Yes
6 Yes.
so it gives you a pattern right there a squared plus b squared equals c squared just fill in the numbers in that way
