Agar \( \angle A=52^{\circ}, \angle E=80^{\circ} \) va \( \angle C=48^{\circ} \) toping. bu uchburchaklarning qolgan burchaklarini 6. \( A A B C=\triangle L M N \). Agar \( A B=5, M N=8 \) va \( A C=9 \) polsa, bu uchburchaklarning qolgan tomonlarini loping.

Un círculo tiene un radio de 5 cm. Si una secante corta este círculo creando segmentos de 3 cm y x cm fuera del círculo, expresa x en función de los radios del círculo.

The lines represented by the equations \( 20 y-12 x=-160 \) and \( y=\frac{3}{5} x-1 \) are Answer neither parallel nor perpendicular the same line parallel perpendicular

Find the volume of the figure when \( b=4 \mathrm{ft} \) and \( h=6 \mathrm{ft} \). \( \square \mathrm{ft}^{3} \)

(b) Write the inverse of the given statement. A figure is a parallelogram if and only if it is a quadrilateral. If a figure is a parallelogram, then it is not a quadrilateral. If a figure is not a quadrilateral, then it is a parallelogram. If a figure is a quadrilateral, then it is a parallelogram. If a figure is not a parallelogram, then it is not a quadrilateral. If a figure is not a quadrilateral, then it is not a parallelogram.
