Answer:
The solution set is {4, -1}
Step-by-step explanation:
6x²- 18x -18 = 6
6x²- 18x -18 - 6 = 0
6x²- 18x -24 = 0
6(x² - 3x - 4) = 0
6(x - 4)(x + 1) = 0
6 = 0 not true
x - 4 = 0 ; x + 1 = 0
x = 4 x = - 1
The solution set is {4, -1}
Sin S=19/54==>mes S=20.60...° A is false
cos P=19/54==>mes P=69.3993...° B is true
==> C is false
p =√(54²-19²)=50.5470...≈50.55 is true
