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...

When told to find angles when equations are involving sin,cos or tan at a level a range will be provided. You have to find all the angles within the given range. Multiple angles will be found as there wil...
