Answer:

6cm ; 22cm

Step-by-step explanation:

Given that:

Total Length, AD = 28cm

AB =x cm

BC = (x +5)cm

CD = 2x - 1 cm

4x + 4 = 28

4x = 28 - 4

4x = 24

x = 24 / 4

x = 6cm

The length of BD

BD = BC + CD

BD = (x + 5) + (2x - 1)

x = 6

BD = (6 + 5) + (2(6) - 1)

BD = 11 + (12 - 1)

BD = 11 + 11

BD = 22 cm

Please help me on how to solve this, I am confused thank you.<br><br> verify sin(180 °-θ)=sinθ

RideAnS [48]

Answer:

Step-by-step explanation:

sin(a-b)=sina cos b-cos a sin b

sin 180°=0

cos 180°=-1

$sin(180-\theta)=sin 180 cos \theta-cos 180sin \theta \\=0* cos \theta-(-1) sin \theta\\=sin \theta$
