RECEITA
A man stands at P on a vertical cliff and sees a coastguard vessel Rout at sea. If Q is a
point vertically below P at sea level such that PQ = 36 metres, and QR = 100 metres,
calculate the size, in degrees, ofe on the figure (i. e. angle PRQ)

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

a=9
