Question

In a parallelogram ABCD , measure of ∆A is three times the measure of ∆B . find all the four angles​

Answer 1

Answer:

The triangles have to have 3 letters dear.

Answer 2

Answer: LA = LC =60° LB= LD =180°

Step-by-step explanation:

In a //gm opposite angles are equal

So LA=LC and LB=LD

Also sum of all angles is 360°

So LA +LB+LC+LD =360°

It is also given that LA =3LB

So taking LA=3LB 1)

LB=LB 2)

LC=LA=3LB 3)

LD=LB 4)

Add all equations

3LB+LB+3LB+LB= 360°

6LB =360°

LB=60°

LA=LD=3LB=180°

LB=LD=60°
