AnswerThe statment true about the image beThe measure of ∠TRU is 72° .ReasonAs shown in the image∠QRU = 90°∠ TRQ = 18°Now ∠QRU be written as the sum of the ∠ TRQ and ∠TRU .Thus it becomes∠QRU = ∠ TRQ + ∠TRUput the value ∠QRU and ∠ TRQwe get90° = 18 ° + ∠TRUSolving the above∠TRU = 90° - 18°∠TRU = 72 °Therefore the measure of ∠TRU is 72 °.Hence proved...
