Question

What is the answer? ​

Answer 1

Answer:

Required Answer:-

• If $\triangle$ ABC is a isosceles triangle then
• AB=BC

Now Substitute values

$\longrightarrow$$\sf 3x-4=5x-10$

$\longrightarrow$$\sf 5x-10=3x-4$

$\longrightarrow$$\sf 5x-3x=-4+10$

$\longrightarrow$$\sf 2x=6$

$\longrightarrow$$\sf x={\dfrac {6}{2}}$

$\longrightarrow$$\sf x=3$

$\therefore$$\sf AB=3x-4=3\times 3-4=9-4 \\ \sf AB=5units$

Answer 2

Step-by-step explanation:

Side AB and Side BC are the same so we can make them equal to each other:

3x -4 = 5x -10

Subtract 3x from both sides.

-4 = 2x -10

Add 10 to both sides.

6 = 2x

Divide both sides by 2

3 = x

x = 3

Now substitute x in the expression

3x -4

3(3) -4

PEMDAS
