On what did the grimké sisters base their argument for equal rights for women? a. the participation of women in the abolition movement b. the moral nature of human beings c. the principles of matrilineal cultures d. the new economic power women were gaining

angle a = 40.6°

step-by-step explanation:

for any right angle triangle we know the pythagoras theorem reveals

hypotenuse² = height²+base²

by this formula we will calculate the length of hypotenuse

h² = 6²+7²

⇒ h =√36+49 = √85 = 9.22

now from the given triangle sin a = height/ hypotenuse

                                                sin a = 6/9.22 = 0.651

therefore

so angle a = 40.6°

is there options? or is it random words?
