Question

construct a ABC , if LA = 45 degree , LB =30 degree and AB= 7 cm measure the length of the sides BC and CA. Also measure the LC .PLEASE SOLVE THIS PROBLEM plezzz hurry

Answer 1

you can draw with the hlp of these steps
Steps of construction -
1. first draw a line segment AB=7cm
2.then with A as centre construct angle A =45°.
[in triangle ABC
you are given that A=45° and C=75°
so by angle sum property-
45+75+B=180
B=180-120
B=60°]
3.now with B as center construct angle B=60°
4.mark the point of intersection of Angle A and B as C.
thus ABC is the required triangle.

i hope its hlp you
