Answer:

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

The diagram refers the angle bisector theorem.

Hence using this theorem in our given diagram:

\frac{LM}{LN}=\frac{x}{ON}

\frac{18}{10}=\frac{x}{4}

Cross multiplying,

x=4*1.8 = 7.2

Hence the answer is 7.2      :   Answer (A)

Hope it will help :)

Decrease £16870 by 3% Give your answer rounded to 2 DP.
Liono4ka [1.6K]
Just do 16870 x .03 (3% as a decimal) and you'll get 506.10. Subtract that to 16870 and you'll get 16363.90.

Answer:

Scale factor = 7

Step-by-step explanation:

Dilation with scale factor to map HEFG to DABC will be,

Scale factor = \frac{\text{Dimension of Image DABC}}{\text{Dimension of preimage HEFG}}

                    = \frac{\text{Length of CD}}{\text{Length of GH}}

Length of CD = Distance between two points C(0, -7) and D(-7, 0)

                       = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

                       = \sqrt{(-7-0)^2+(0+7)^2}

                       = \sqrt{98}

                       = 7\sqrt{2}

Length of GH = Distance between G(0, -1) and H(-1, 0)

                       = \sqrt{(-1-0)^2+(0+1)^2}

                       = \sqrt{2}

Scale factor = \frac{7\sqrt{2} }{\sqrt{2} }

                    = 7
