Question

If cosx=6/10 then what's is sinx?

Answer 1

Step-by-step explanation:

cosx=6/10

sinx=√1-cos²x

sinx=√1-36/100

sinx=√64/100

sinx=4√4/10

Answer 2

Answer:

• $sinx^{2} =1-cosx^{2} \\sinx^{2} =1-(\frac{6}{10})^{2} \\ =1-\frac{36}{100} \\ =\frac{100-36}{100} \\ =64/100\\\sqrt{sinx^{2} } =\sqrt{\frac{64}{100} } \\sinx=\frac{8}{10}$
