Даны треугольники \( O A B \) и \( O C D \), в которых сторонь \( O A \) и \( O D \) равны, угол \( A \) равен углу \( D \). Найдите сторону \( O B \), если \( O C=5 \) см и \( A B=D C \).

Identify the perimeter and area of a square with diagonal length 24 in. Give your answer in simplest radical form.

A picture frame is 24 in . wide and 36 in. high. Will a picture with a 40 in. diagonal fit in it? Identify the correct explanation. Because \( 43.3>40 \), it is NOT possible that the picture fits in the frame. Because \( 36<46.6 \), it is NOT possible that the picture fits in the frame. Because \( 43.3>40 \), it is possible that the picture fits in the frame. Because \( 36<46.6 \), it is possible that the picture fits in the frame.

4. The diagonals of a rhombus are .......... \( \begin{array}{llll}\text { (a) Perpendicular and not equal in length. (b) Equal in length and not perpendicular } \\ \text { (c) Equal in length and perpendicular, } & \text { (d) Neither equal in length nor perpendicular. } \\ 5 \text { If } 8 x=24 \text {, then what is the value of } 3 x \text { ? } \\ \begin{array}{llll}\text { (a) } 3 & \text { (b) } 6 & \text { (c) } 9 & \text { (d) } 12\end{array} \\ \text { is The measure of the central angle of the circular sector which represent } 35 \% \text { of a circle } \\ \begin{array}{llll}\text { (a) } 35^{\circ} & \text { (b) } 108^{\circ} & \text { (c) } 120^{\circ} & \text { (d) } 126^{\circ}\end{array}\end{array} \).
