Answer 4

someone help!!!

Answer 5

hmmm have you covered the Law of Cosines yet?

Answer 6

yes. I tried solving it but I don't get the any correct answers.

Answer 7

ok so so let us use the law of cosines to get angle T

so we have all sides so sides t = 7 s = 10 r = 11

thus \(\bf \textit{Law of Cosines}\\ \quad \\
t^2 = {\color{blue}{ r}}^2+{\color{red}{ s}}^2-(2{\color{blue}{ r}}{\color{red}{ s}})cos(T)\\ \quad \\

cos(T)=\cfrac{{\color{blue}{ r}}^2+{\color{red}{ s}}^2-t^2}{2{\color{blue}{ r}}{\color{red}{ s}}}\implies \measuredangle T=cos^{-1}\left(\cfrac{{\color{blue}{ r}}^2+{\color{red}{ s}}^2-t^2}{2{\color{blue}{ r}}{\color{red}{ s}}}\right)
\\ \quad \\
\measuredangle T=cos^{-1}\left(\cfrac{{\color{blue}{ 11}}^2+{\color{red}{ 10}}^2-7^2}{2{\color{blue}{ (11)}}{\color{red}{ (10)}}}\right)\)
