Answer:
34.64
Step-by-step explanation:
take tan value and solve the triangle
SOH,CAH, TOA so it would be TANGENT since it would be Opposite over Adjacent. Tan(15) = 9/a put Tan(15) onto your calculator it would be .267949 round that to .27 = 9/a cross multiply
a = 33.588. C is the correct answer.
Answer:
x - y + z = 8
2x +3y -z= -2
3x - 2y -9z = 9
Step-by-step explanation:
[1 - 1 1 8]
[2 3 -1 -2]
[3 -2 -9 9]
EQUATION OF A CIRCLE: (x-h)² + (y-k)² =r²
= (x+1)² + (y-4)² =3
