Question

the value of sin10°cos80°+cos10°sin80°=?​

Answer 1

Explanation:

sin10 cos80 + cos10 sin80

= cos(90-10) cos80 + sin(90-10) sin 80

= cos80.cos80 + sin80.sin80

= cos^2 (80) + sin^2 (80)

we know....

${sin}^{2} \alpha + {cos}^{2} \alpha = 1$

so,........

cos ^2(80) + sin^2 (80) = 1

so, ur answer is 1........

mark it as brainliest.....
