Question

in triangle ABC angle C=angle A ,AC-AB=3 and it's perimeter is 15 cm Find AC​

Answer 1

Answer:

7CM

Step-by-step explanation:

GIVEN: ANGLE A=ANGLE B

THEREFORE AB = BC

GIVEN: AC - AB = 3

AC = AB + 3

PERIMETER OF ∆ABC = 15

AB + BC + AC = 15

AB + AB + 3 + AB = 15

3AB = 12

AB = 4CM

NOW AC - AB = 3

AC - 4 = 3

HENCE AC=7CM
