An obtuse triangle is a triangle which has one obtuse angle. <span>
Obviously, only a single angle in a </span>triangle<span> can be </span>obtuse<span> or it wouldn't be a </span>triangle.
Hope that helps you
It is 7.5, think like 100÷4
First off, see how much 8700 as principal, yields at 3% APR
that is
![\bf \qquad \textit{Simple Interest Earned}\\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\\ P=\textit{original amount deposited}\to& \$8700\\ r=rate\to 3\%\to \frac{3}{100}\to &0.03\\ t=years\to &1 \end{cases}](https://tex.z-dn.net/?f=%5Cbf%20%5Cqquad%20%5Ctextit%7BSimple%20Interest%20Earned%7D%5C%5C%5C%5C%0AI%20%3D%20Prt%5Cqquad%20%0A%5Cbegin%7Bcases%7D%0AI%3D%5Ctextit%7Binterest%20earned%7D%5C%5C%0AP%3D%5Ctextit%7Boriginal%20amount%20deposited%7D%5Cto%26%20%5C%248700%5C%5C%0Ar%3Drate%5Cto%203%5C%25%5Cto%20%5Cfrac%7B3%7D%7B100%7D%5Cto%20%260.03%5C%5C%0At%3Dyears%5Cto%20%261%0A%5Cend%7Bcases%7D)
it will yield some amount
subtract that amount from 393
the difference is how much the yield will be on the 6% investment
so
![\bf \qquad \textit{Simple Interest Earned}\\\\ I = Prt\quad \begin{cases} I=\textit{interest earned}\\ P=\textit{original amount deposited}\to& \$8700\\ r=rate\to 3\%\to \frac{3}{100}\to &0.03\\ t=years\to &1 \end{cases} \\\\\\ \implies \boxed{?}\\\\ -----------------------------\\\\ \textit{how much to invest at 6\%?} \\\\\\ ](https://tex.z-dn.net/?f=%5Cbf%20%5Cqquad%20%5Ctextit%7BSimple%20Interest%20Earned%7D%5C%5C%5C%5C%0AI%20%3D%20Prt%5Cquad%20%0A%5Cbegin%7Bcases%7D%0AI%3D%5Ctextit%7Binterest%20earned%7D%5C%5C%0AP%3D%5Ctextit%7Boriginal%20amount%20deposited%7D%5Cto%26%20%5C%248700%5C%5C%0Ar%3Drate%5Cto%203%5C%25%5Cto%20%5Cfrac%7B3%7D%7B100%7D%5Cto%20%260.03%5C%5C%0At%3Dyears%5Cto%20%261%0A%5Cend%7Bcases%7D%0A%5C%5C%5C%5C%5C%5C%0A%5Cimplies%20%5Cboxed%7B%3F%7D%5C%5C%5C%5C%0A-----------------------------%5C%5C%5C%5C%0A%5Ctextit%7Bhow%20much%20to%20invest%20at%206%5C%25%3F%7D%0A%5C%5C%5C%5C%5C%5C%0A)
