Explanation:

I really didn't know the answer of this cauz...i did not encounter this some kind of topic or lesson ...Will Im just a high school student , so maybe I still encounter this in the future.

I just made a research on it and summarize it all .

I hope this is correct .

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°

the answer is lower nubia. plz mark brainliest i am trying to improve rank.
