Find the exact solutions of the given equations, in radians, that lie in the interval [ 0, 2π). cos^2 x - sin^2 x = 0

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5
