The base of a square-based pyramid has side lengths 4 cm. N is the central point of the base.
The sloped height of the pyramid is 16 cm.
Calculate the angle that side AR makes with the base to 1 dp.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

i got 142 as my answer
