Solve the quadratic equation below x2−25=0

1 answer:

4 0

X= 12.5, this is because you need to add 25 to the other side of the equation to make 2x = 25 and then divide both sides by 2 to get x=12.5

Without using trignometery tables find value of , cos70/sin20+cos57.cosec33 - 2cos60

Helen [10]

Here is some thoughts on this:

cos 57 = sin (90-57) = sin 33

so cos 57 . cosec 33 = cos 57 / sin 33 = sin 33 / sin33 = 1

2 cos 60 = 2 * 1/2 = 1

so the last 2 parts work out to 0

now we have to find cos 70 / sin 20

sin 20 = cos 70 so this comes to 1

so finally the answer is 1
