Given:
In the given triangle,
With respect to y, Perpendicular = 10 cm and Base = 8 cm
To find the value of y.
Formula
By Trigonometric Ratio we get,

Now,
Putting the values of perpendicular and base we get,

or, 
or, 
Rounding off to the nearest tenth, we have;

Hence,
The value of y is 51.3°.
Uhh my brains hurts looking at that
Both 28 I think I just multiplied 7×4 and on the light side is still the same length so that means that is also 4 for A
Noice that means points for me lol
Step-by-step explanation:
f(x)=3x²-3x
f(-3)=3(-3)²-3(-3)
=3(9)+9
=27+9
=36
g(x)=5x-1
g(-7)=5(-7)-1
=-35-1
=-36
