Question

The two equal sides of an isosceles triangle are (5x + 2) cm and (3x + 12) cm. If the third side is 3x cm, find the third sides of the triangle. ​

Answer 1

Answer:

Step-by-step explanation:

If the two equal sides are:

5x+2 and 3x+12

Then:

5x+2 = 3x+12

Collect like terms

5x - 3x = 12 - 2

2x = 10

x = 10

Third side = 3x

x = 10

3x = 3×10

= 30cm

Second side = first side

5x + 2 = 3x + 12

5(10) + 2 = 3(10) + 12

= 52cm
