Given: ∆abc, ab = bc, m∠1

AB = 7, BC = 7 and AC = 11

Step-by-step explanation:

Let AB = BC = a and CA = b

Now, given that the perimeter of the triangle is 25.

So, 2a + b = 25 (1)

And 4 is the difference between the two unequal sides.

Hence, b - a = 4 (2)  

⇒ 2b - 2a = 8 (3)

Now, solving equations (1) and (3) we get, 3b = 25 + 8 = 33

⇒ b = 11

Hence, from equation (2) we get a = b - 4 = 7

Therefore, AB = 7, BC = 7 and AC = 11 (Answer)

Answer with Step-by-step explanation:

1.In triangle ABC

AB=BC

Let AB=BC=x and AC=y

Perimeter of triangle ABC=25

...(1)

...(2)

Adding equation (1) and (2)

Substitute x=9.67 in equation (2)

2.

By using triangle angle sum property

Substitute the values then we get

Substitute the value

(Side ST is opposite to angle R, Side RT is opposite to angle S

 (side RS is opposite to angle T)

When a>b

Then , opposite side of a> opposite side of b

RS

3.

By using triangle angle sum property

Substitute the values then we get

Substitute the value

RT>RS

RS>ST

ST

answer: its because of life

step-by-step explanation: i dont know

The value of is AB = BC = unit , AC is unit  .

Step-by-step explanation:

Given as :

In a triangle ABC ,

Let The three sides be AB , BC , CA

Side AB = Side BC , ∠B = 90°

Perimeter of ΔABC =25 unit

Or, AB + BC + CA = 25 unit  

Or, AB + AB + CA = 25 unit

i.e 2 AB + CA = 25 unit                    .....1

And Difference between two sides = 4

So, AB - CA = 4 unit                        .......2

Now, According to question

From eq 1 and eq 2

(2 AB + CA) + (AB - CA) = 25 unit + 4 unit

Or, (2 AB + AB) + (CA - CA) = 29

Or, 3 AB + 0 = 29

∴ AB = unit

∵ BC = AB

So, BC = unit

Again

∵ AB - CA = 4 unit

So, AC = AB - 4

Or, AC = unit - 4 unit

Or, AC = unit

i.e AC =   unit

So, The value AB = BC = unit , AC = unit

Hence, The value of is AB = BC = unit , AC is unit  . Answer
