Question

the unequal side of isoceles triangle is 15m . if the perimeter is 45m find the length of equal side​

Answer 1

Answer:

first side=second side=15m

Step-by-step explanation:

let the equal sides of isoceles triangle each is x m

Now

perimeter of isoceles triangle= first side +second side+ third side

45= x+x+15

2x+15=45

2x=45-15

x=30/2

x=15m

First side=15m second side=15m third side=15m

Answer 2

★Given that,The unequal side of isoceles triangle is 15m,the perimeter is 45m find the length of equal side.

☯️ To Find: the length of equal side

__________________________________________

solution:

now,let the equal sides be x

so,

$: ⟹ x + x + 15 = 45 \\ \\ : ⟹ 2x + 15 = 45 \: \: \: \: \: \: \\ \\ : ⟹ 2x = 45 - 15 \: \: \: \: \: \\ \\ : ⟹ 2x = 30 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ : ⟹ x = \cancel \frac{30}{2} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ : ⟹  \blue{\boxed{ \purple{x = 15}}}$

hope this helps.!
