Can someone me. i need to write a poem about the origins of drill in the military, and it's purpose of it in the military and daily life.(i really need )(if you me i can make you a brainliest) : )

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°

it was a act of seld fesnse more over it was a peace treaty between the fogein contunries.
