Standard Interior Angles. M Worksheet by Kuta Software LLC Geometry ID: 1 Name_____ 5 s2F0 u13Y NKWu9tSa6 7SFoyf dtZwfamrwes nL sLMCD.3 a rAVl7lO Xr2i 7g9h2t Qss mr1e Mse5rUvuejdZ. All three angles have to add to 180, so we have: \(\angle {\text{B }} + {\text{ 31 }} + {\text{ 45 }} = {\text{ 18}}0\), \(\angle {\text{B }} + {\text{ 76 }} = {\text{ 18}}0\) (combine like terms), \(\angle {\text{B }} = {\text{ 1}}0{\text{4}}^\circ \). However, the triangle angle sum theorem states that the sum of the three interior angles in a triangle is always 180. Plug it and compute the measure of the indicated angle in Part A and the measure of four angles in Part B. To solve, remember that \(\Delta ABC\) is an equiangular triangle, so all three angles are equal. Triangle Angle Sum Practice Triangle Angle Sum Practice ID: 1644432 Language: English School .
