Answer: 80
Step-by-step explanation:
Sin x = cos (90-x)
Like sin 30 = cos (90-30) =cos 60
So
90-x=90-80
Then
X=80
Verify your solution by finding the sum of the angles of sin and cos, it will be 90
If it is continuous that means it covers all values of both y and x meaning your domain is { all real values of x }
Range is { all real values of y}

<span> 5.1 </span> Pull out like factors :
<span> 75x4 + 3x3y + 15x2y2</span> = <span> 3x2 • (25x2 + xy + 5y2)</span>
Trying to factor a multi variable polynomial :
<span> 5.2 </span> Factoring <span> 25x2 + xy + 5y2</span>
Try to factor this multi-variable trinomial using trial and error<span>
</span>Factorization fails
Final result :<span> 3x2 • (25x2 + xy + 5y2)
