Question
Determine the remaining sides and angles of each triangle $A B C$.(Angle can't copy)
Step 1
We know that the sum of the angles in a triangle is $180^{\circ}$. So, we subtract the sum of the given angles from $180^{\circ}$ to find angle $A$. \[A = 180^{\circ} - (B + C) = 180^{\circ} - (52^{\circ} + 29^{\circ}) = 99^{\circ}\] Show more…
