draw a line BC=7 cm construct an angle of 75 degree on B extend the line to X cut an arc of 13 cm mark it as D join CD draw perpendicular bisector of CD mark A on BD join AC hence ABC is the required triangle
Yasmin:
ok
should I take more than half of CD?
yes and draw arc on both sides
Ok
Can u pls try to solve other sums?
I've posted more
i want to ask if you have any other book
like RDSHARMA
helpp

2. Construct angle of 75 degree at B using protractor.
3. Draw line BD= 13 cm.
4. Join CD.
5. Bisect line CD and mark as E.
6. Draw perpendicular at E to intersect BD at A.
7. Join AC to get triangle ABC.
