the heart graph is not a function
=======================
-45,-55,-65
=======================
A(30) = -1 + (30 - 1) * 2 = -1 + 29 * 2 = -1 + 58 = 57 <==

Answer:
Step-by-step explanation:
Triangle DEF is a right angle triangle.
From the given right angle triangle
DF represents the hypotenuse of the right angle triangle.
With m∠D as the reference angle,
DE represents the adjacent side of the right angle triangle.
EF represents the opposite side of the right angle triangle.
To determine EF, we would apply the Sine trigonometric ratio
Sin θ = opposite side/hypotenuse. Therefore,
Sin 26 = EF/4.5
0.44 = EF/4.5
EF = 4.5 × 0.44 = 1.98 yo 2 decimal places
Answer:
sinA = 3/5 cosA = 4/5 tanA =3/4
Step-by-step explanation:
SinA = Opposite/Hypotenuse
CosA= Adjacent/Hypotenuse
TanA = Opposite/Hypotenuse
