Question

In triangleABC, angleA=angleC,AC=5 and BC=4.Then the perimeter of angleABC is​

Answer 1

Answer:

13units

Step-by-step explanation:

abc is an isoceles triangle since angle a = angle c

ab = bc

ab = 4units

perimeter

= 5 + 4 + 4

= 13 units

Answer 2

since two angles are equal ,therefore it is a isosceles triangle,because sides opposite to equal angles are equal.

since,angle A=angle C

therefore,

AB =BC=4

perimeter of ∆=sum of all sides

=AB+AC+BC

=4+5+4

=13

hope it helps
