5x-7x < -6+3 => -2x < -3 => x > 3/2

6x^2 - 10x + 12x - 20

6x^2 + 2x - 20

3y-p=h(2+y)

3y-p=2h+hy

3y-hy=2h+p

y(3-h)=2h+p

y=(2h+p)/(3-h)

All angles in a triangle add up to 180 degrees. In a right angled triangle, we know one angle is 90 degrees. In the question, it is given that another angle is 63 degrees. So the remaining angle must be 1...
