Question

v) If sin 0
20
29
then find cos 0​

Answer 1

Answer:

sin 0 = 20 / 29

We know , sin square theta + cos square theta = 1

(20/29) square + cos square theta = 1

400 / 841 + cos square theta = 1

cos square theta = 1 - 400 / 841

cos square theta = 841 - 400 / 841

cos square theta = 441 / 841

cos theta = 21 / 29

hope it's help you..
