Direct variation is of the form
y= mx
2x-4y = 0
2x = 4y
4y = 2x
y = 2/4 x
y =(1/2)x
which is indeed of the form y = mx
Hence, the equation does represent direct variation.
in y= mx,
the constant of variation is m
so in y = (1/2)x
the constant of variation is 1/2
There could be 2 possible shapes that could’ve been drawn.
A rectangle, or a square.
All of their angles are 90° angles, which are right angles.
Hope this helped!

Answer:
105.0°, 255.0°
Step-by-step explanation:
Many calculators do not have a secant function, so the cosine relation must be used.
sec(θ) = -3.8637
1/cos(θ) = -3.8637
cos(θ) = -1/3.8637
θ = arccos(-1/3.8637) ≈ 105.000013°
The secant and cosine functions are symmetrical about the line θ = 180°, so the other solution in the desired range is ...
θ = 360° -105.0° = 255.0°
The angles of interest are θ = 105.0° and θ = 255.0°.
