<u>Answer:</u>
An obtuse triangle has two angles 45 and 18. The value of the unknown angle is ![117^{\circ}](https://tex.z-dn.net/?f=117%5E%7B%5Ccirc%7D)
<u>Solution:</u>
Given that two angles of an obtuse triangle is 45 and 18.
Third angle is θ
We are asked to find the value of third unknown angle theta
According to <em>angle sum property of triangle</em>, sum of three angles of triangle is ![180^{\circ}](https://tex.z-dn.net/?f=180%5E%7B%5Ccirc%7D)
This means in our case sum of 45, 18 and θ should be ![180^{\circ}](https://tex.z-dn.net/?f=180%5E%7B%5Ccirc%7D)
![\begin{array}{l}{=>45+18+\theta=180} \\ {=>\theta=180-63=117^{\circ}}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B%3D%3E45%2B18%2B%5Ctheta%3D180%7D%20%5C%5C%20%7B%3D%3E%5Ctheta%3D180-63%3D117%5E%7B%5Ccirc%7D%7D%5Cend%7Barray%7D)
Hence value of unknown third angle of an obtuse triangle is
