B PQRS is a quadrilateral in which PR = 10cm, Perpendiculars from sand on PR are 3.4cm
and 4.6 cm respectively. Calculate the area of
the quadrilateral.​

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
