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
It’s should be 12.04 after you do all the math and add it up
ANSWER :
14x-x^2 = 33
Step-by-step explanation:

14x-(x)^2 = 33
Answer:
well its a triangle so
40 divide by 20 is 2
but you have to mutiply that 2 by 2
