Multiple Choice 1 point Triangle \( A B C \) was translated 2 units to the right and 3 units down. Which rule describes the translation that was applied to triangle \( A B C \) to create triangle \( A^{\prime} B^{\prime} C^{\prime} \) ? F \( (x, y) \rightarrow(x-3, y+2) \) G \( (x, y) \rightarrow(x+2, y-3) \) H \( (x, y) \rightarrow(2 x,-3 y) \) J \( (x, y) \rightarrow(-3 x, 2 y) \)

7a somma dei raggi di due circonferenze misura 15 cm e uno è i \( \frac{2}{3} \) dell'altro. Determina la lunghez- za delle due circonferenze. \[ [12 \pi \mathrm{~cm} \approx 37,68 \mathrm{~cm} \mathrm{e} 18 \pi \mathrm{~cm} \approx 56,52 \mathrm{cm]} \]

3] (a) If the distance between the point \( (a, 7) \) and the point \( (0,-5) \) equals 13 length units find the value of a

47. The measure, in degrees, of each interior angle of a regular polygon with \( n \) sides is given by \( \frac{(n-2) \mid 80}{n} \). What is the sum of the measures of the interior angles of a regular octagon?

2] \( A B C D \) is aparallelogram, \( m(\angle A)+m(\angle C)=200^{\circ} \), then \( m(\angle B)=\ldots(50,80,100,160) \)

2 complementary angles have the sum of ............... \( 360^{\circ} \) B. \( 90^{\circ} \) C. \( 180^{\circ} \) D. \( 60^{\circ} \)
