The first side of a triangle measures 4 in. less than the second side, the third side is 3 in. more than the first side, and the

Firdavs [7]

Answer:

$\boxed{\frac{23}{3} ~in}$ or $\boxed{7,7~in}$

Step-by-step explanation:

Suppose, the first side is a, the second side is b, and the third side is c. So:

→ a = s - 4

→ b = s

→ c = (s - 4) + 3

→ a + b + c = 15

First step, find the value of s

a + b + c = 15

(s - 4) + s + (s - 4) + 3 = 15

3s - 5 = 15

3s = 15 + 5

3s = 20

$s = \frac{20}{3}$

So, the third side is

c = (s - 3) + 4

c = s + 1

c = $\frac{20}{3} + 1$

$c = \frac{23}{3}$

Happy to help :)

A 70 cm long stick is cut into two parts in such a way that the longer part is 20 cm longer than the shorter part. How long is e

Dahasolnce [82]

Answer:

Long part= 45

Short part= 25

Step-by-step explanation:

Let the short part of the stick be x

Let the long part be x+20

The total length of the stick is 70cm

x + (x+20)= 70

x+x+20= 70

2x+20= 70

2x= 70-20

2x= 50

x= 50/2

= 25

Longer part length= 20+25

= 45

The short part is 25
