Question

I need a quick answer. I will appreciate your efforts

Answer 1

Answer:

10.5 cm

Step-by-step explanation:

12÷9= 1.3 (1dp)

14÷(12÷9)= 10.5cm

Answer 2

Answer:

y = 10.5 cm

x = 80 degree

Step-by-step explanation:

Our approach is find measures first and y is our missing measure.

To find y

PQRS : ABCD   is in ratio the same as CD : RS

We need to work out CD : RS to find measures of  AD : SP

To find ratio we look at side measures first

CD : RS  = 12 : 9

12/9 = 1.333333

So that AD : SP   = 14 : ?

14 / 1.333333 = 10.50000

AD : SP =  14 : 10.5

y = 10.5 cm

To find x

We are given opposite angles and know with quadrilaterals they both share same opposite diagonal length ratios and share same opposite angles.

Where two angles are always in pairs given 100 degree can be multiplied by 2 and use the equation.

360 - (100 x 2) / 2  =  (360 - 200) / 2 = 160/2 = 80 degree

x = 80 degree
