Our angle teta is:
teta = 3pi/4

since that is larger than pi/2 but less than pi that means that our angle lies in II quadrant (x negative y positive)

sin(3pi/4) = √2/2
cosine and tangent of that angle must be negative because of position of the angle.

cos(3pi/4) = -√2/2
tan(3pi/4) = -1

What should be subtracted from

pychu [463]

<u>-5a²+13ab</u> should be subtracted.

<h3>Step-by-step explanation:-</h3>

Based on the given conditions, formulate,

$→- {a}^{2} - 4 {a}^{2} + 13ab$

$→-({a}^{2} - 4 {a}^{2}) + 13ab$

Taking the coefficients or numbers, we get,

$→(- 1 - 4) {a}^{2} + 13ab$

$→ - 5 {a}^{2} + 13ab$
