Chapter 10: Q.15 (page 540)

Find the unknown side length of the triangle given the perimeter P. Then classify the triangle by its side lengths.

P=49in.

Short Answer

Expert verified

The length of the unknown side of the triangle is 19 in.

The triangle is a scalene triangle.

Step by step solution

01

Step 1. Given Information.

Perimeter of the triangle is given as P=49in.

Length of one side is 18 in.

Length of second side is 12 in.

02

Step 2. Calculation.

Let the length of the unknown side be as x.

x+18+12=49

Now add both numbers together,

x+30=49

Subtract 30 from both the sides

x+30-30=49-30

This gives us

x=19in.

03

Step 3. Conclusion.

The length of the unknown side of the triangle is 19 in.

Since, all the lengths of the three sides are different, hence it is a scalene triangle.
