I think the fourth option is the answer. It wi give you the Side angle side postulate.
Answer:
x ≈ 4.6
Step-by-step explanation:
Reference angle = 75°
Opposite side to reference angle = 17
Adjacent side = x
Applying TOA:
Tan 75 = opp/adj
Tan 75 = 17/x
Multiply both sides by x
x*Tan 75 = 17
Divide both sides by Tan 75
x = 17/Tan 75
x ≈ 4.6
f(x)=-3x^2-1
f(-2)= -3(-2)²-1=-3·4-1= - 13
