Stabilisci se le seguenti quaterne di numeri rappresentano le misure in centimetri delle lunghezze dei lati di un quadrilatero. Se si, calcola it perimetro del quadrilatero. a \( 13,24,7,41 \) b \( 3,10,8,22 \) e \( 11,9,9,15 \)

2. Titik \( L(9,-2) \) dicerminkan terhadap \( x=2 \) kemudian dilanjutkan translasi \( T\binom{-2}{4} \), bayangan titik \( L \) adalah \( \ldots \) \( \begin{array}{llll}\text { A. }\binom{-5}{2} & \text { B. }\binom{-3}{4} & \text { C. }\binom{7}{6} & \text { D. }\binom{7}{2}\end{array} \)

1. Bayangan dari titik \( (3,6) \) yang ditranslasikan \( T\binom{-4}{5} \) kemudian dilanjutkan refleksi terhadap sumbu \( x \) adalah \( \ldots \) \( \begin{array}{llll}\text { A. }\binom{7}{11} & \text { B. }\binom{1}{11} & \text { C. }\binom{-1}{-11} & \text { D. }\binom{-1}{11} \\ \text { E. }\binom{-7}{-11}\end{array} \)

3. Bayangan dari titik \( \mathrm{C}(-2,3) \) yang dirotasikan 90 dengan pusat \( (1,2) \) dilanjutkan rotasi 270 searah dengan jarum dan pusat \( (0,0) \) adalah... A. \( (0,-1) \) B. \( (1,0) \) C. \( (0,5) \) D. \( (-1,0) \) E. \( (0,-5) \)

Teresa needs to cut a triangular piece of tile for a mosaic. In order to cut it properly, she needs to know the measure of the unknown angle? \( { }^{\circ} \) as shown in the figure. The lengths of \( K L, L M \), and \( M K \) are 105 millimeters, 123 millimeters, and 182 millimeters respectively. What is the value of the unknown angle? (Round your answer to the nearest degree if necessary.)

Si un ángulo central mide 50 grados, ¿qué medida tiene el arco que este angulo subtende?
