Question

angle ABC ~ angle LBN In angle ABC, AB=5.1cm , LB-40 BC=4.8cm, AC/LN = 4/7. Construct angle ABC and Angle LBN​

Answer 1

Answer: Step-by-step explanation:

Draw a line segment BC with a scale of 4.8 cm  

From point B measure an angle 40°.  

From point B with a measure of 5.1 cm draw an arc along the angle marked.  

Mark the point as A  

Join AB and AC.  

Hence the required Δ ABC.  

Divide the line segment BC into 4 equal parts.  (4.8 ÷ 4 = 1.2 cm)  

Mark a point N on the line segment BC such that BN is seven times the of each segment BC.  

Draw a line parallel to AC, through N.  

Name the point of line as L.  

Join LN.

Hence the required Δ LBN
