To solve the problem of constructing triangle ABC with the given specifications and then creating a larger triangle, follow these steps: ### Step 1: Calculate the Missing Angle First, we need to find angle C. We know that the sum of angles in a triangle is 180 degrees. - Given: Angle A = 105°, Angle B = 45° - Therefore, Angle C = 180° - (Angle A + Angle B) = 180° - (105° + 45°) = 30°. ### Step 2: Draw Side BC ...
