U.S. Treasury and municipal bonds are those which are guaranteed as opposed to the agency bonds which are issued by a government agency. Some examples of such agencies are like Fannie Mae, Freddie Mac, Sallie Mae and the Federal Home Loan Banks.

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 d trust me
