Question

If cos theta equal 21 upon 29 then the value of sin theta will be

Answer 1

cos square theta is equal to 20 /29 whole square and then subtract this value from 1 to get sin square theta and then take under root you will get sin theta we are using the identity sin square theta + cos square theta is equal to 1 then sin square theta equal to 1 minus cos squared theta and sin theta will be equal to under root 1 minus cos square theta ...

Answer 2

Sin^(2)theta + cos^(2)theta = 1
