The diagram shows the small sector lmn
inside the big sector opq of radius 160 cm.
the angle of both sectors are 1 radian.
calculate
(a) the radius of small sector
(b) the perimeter of a small sector
(c) the area of a shaded region

Figure lmno is located at l (1, 1), m (4, 4), n (7, 1), and o (4, −2). use coordinate geometry to best classify quadrilateral lmno.

For how answer my question this will be the last question can you answer in math subject

A, b, c, and d have the coordinates (-8, 1), (-2, 4), (-3, -1), and (-6, 5), respectively. which sentence about the points is true? a. a, b, c, and d lie on the same line. b. and are perpendicular lines. c. and are parallel lines. d. and are intersecting lines but are not perpendicular. e. and are parallel lines.
