3x - y = -40
x + 2y = -4
x = 1st number
y = second number
Josie has a cord that is 9 feet long
If she wants to cut it into 11 pieces then each piece will be (9 ÷ 11) which is 0.81
Answer:
Step-by-step explanation:
By applying Pythagoras theorem in the triangle given in the picture,
(Hypotenuse)² = (leg 1)² + (leg 2)²
PO² = (15)² + 8²
PO² = 225 + 64
PO = √289
PO = 17
By applying sine rule in the given triangle,
sin(x°) =
=
cos(y°) =
=
Relation between the ratio of sin(x) and cos(x) will be,
Your answer would be A)
Hope this helps (:
