if 0< theta < 90 and tan theta equals pie3/2, find cos theta.i put 2/pie 7 but i was wrong please correct.

Answer 1

I don't know what you mean by
pie3/2 and by 2/pie 7

do you mean 3pi/2 ? or ???
2/pie 7 is even more confusing.

remember tan(theta) = opposite/ adjacent

so you can form a right-angled triangle in the first quadrant, fill in those two sides, then use Pythagoras to find the hypotenuse.
And cos(theta) = adjacent/hypotenuse

Answer 2

my nswers was 2/pi7 but i ws wrong
