All of the following statements are true about the rosetta stone, except

a. it was discovered by a french soldier.
c. it was written in greek and egyptian.
b. it was written by priests.
d. it to solve the mystery of the egyptian calendar.

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°

answer; i believe the correct answer is (desert storm);
