Question

Construct ∆ ABC such that ( BC ) = 6cm and angle ABC = 100° and angle BCA =30° Draw​

Answer 1

Step-by-step explanation:

Draw a triangel and address the points as A,B,C

draw the base of BC=6cm with the help of scale

• <ABC=100
• <BCA=30

now,

• <ABC+<BCA+<CAB=180(Angle sum property)

100+30+<CAB=180

130+<CAB=180

<CAB=180-130

<CAB=50 degree

answer of angle <CAB=50
