Thr four angles of a quadrilateral L are in the ratio 5:2:3:8find the angle
Anuta_ua [19.1K]
Ratio = 5:2:3:8
Sum of all internal angles = 360°
5x + 2x + 3x + 8x = 360°
18x = 360°
x = 20°
Therefore,
5x = 100°
2x = 40°
3x = 60°
8x = 160°
5:2:3:8 :: 100:40:60:160.

____ [38]

Answer:

6 units²

Step-by-step explanation:

The coordinates (1,1) (1,4) (5,1)  form a right triangle as shown in the graph below

The base is  is (1,1) and (5,1) so the length is 5-1 or 4 units

The height is (1,1) and (1,4) so the height is 4-1 or 3 units

Area of a triangle is given by

A = 1/2 bh

    = 1/2 (4*3)

    = 1/2 *12

    = 6 units^2
