The second one is your answer
C = 180 - A - B
And
C = 180 - (A+B)
Hope I can help you :)
Brainliest answer :)) ?
Answer:
x= C-a/b
Step-by-step explanation: Ik alllLlLLlllLlLL
(my other account is actingqueen2468 but i forgot my password)
Tgα = tan(α) = sqrt(2)/1 = opposite/ adjacent
opposite = sqrt(2)
adjacent = 1
hypotenuse = sqrt(opposite^2 + adjacent^2)
= sqrt(sqrt(2)^2 + 1^2) = sqrt(3)
sin(α) = opposite/hypotenuse
= sqrt(2)/sqrt(3)
cos(α) = adjacent/hypotenuse
= 1/sqrt(3)
now we can calculate the value of
5sin²α+3cos²α / 3sin²α-5cos²α
... do the math
