Which source would give the most accurate number of slaves in the colonies? select one: a. government records of the sale of slaves b. paintings and images of slaves on plantations c. writings about slave life from eyewitnesses d. stories passed down from generations of slaves

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 would be B
