For all those peeps who delete my free questions, listen up, im only trying to HELP YOU GET MORE FREE POINTS ok so now thats over withbye

trust me i get itits happend with me too

Explanation:

I understand you are trying to be helpful but people need help on questions so it is best if we just get our points fairly

Explanation:

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°
