Answer:
10.39 or 10.4
Step-by-step explanation:
Since this is a right triangle, you have the formula a squared +b squared = c squared where a and b are the legs and c is the hypotenuse. You plug in the values and you should get sqrt of 108 for x.
-14,2
Because if you multiply -14*2 you get -28 and if you add -14+2 you get -12. Hope this helps
= 3 - 3cos x - 2(1- cos^2 x)
= 2cos^2 x - 3cos x + 1
=(cos x -1)(cosx - 1/2)
now cos x = 1 or cos x= 1/2
draw a graph we get = + ve values
hence .. 0 ,180,360 and 60,240, degrees in range x<2pi
Hello,
Shall we begin?
= 2 + 2×9÷3+10-45+21
= 2 + 18 : 3 + 10 - 45 + 21
= 2 + 6 + 10 - 45 + 21
= - 6
Answers: - 6
