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

Can you answer this question ?
Elden [556K]

Answer:

k = -14

Step-by-step explanation:

We should cross-multiply

9/(k -  7)  =  6 / k

9*k  = 6 * (k - 7)

9k = 6k  - 42

9k - 6k = -42

3k = -42

k = -14
