Hope it will be helpfull to you
Step-by-step explanation:
(i) Draw a line segment which is sufficiently long using ruler.
(ii) Locate points X and Y on it such that XY=3.5cm.
(iii) At Y, construct a line segment YW, sufficiently large, such that ∠XYZ=100˚ ; use protractor to measure 100˚
(iv) With Y as centre and radius 5.5 cm, draw the line cutting YW at Z; join XZ.
⇒ Then XYZ is the required triangle.
