Question

the value of sin80-cos80 is negative true or false answer with justification please​

Answer 1

Answer:

false

Step-by-step explanation:

we can write it as

sin80-sin10

but we know sin value increases when the angle increases in 1st quadrant

so sin80>sin10

hence sin80-sin10 is positive

Answer 2

Answer:

This statement is false because the value of cos decreases from 0degree to 90 degree and value of sin increases

so the value of sin 80 is greater than cos 80 therefore it is positive
