The interior angles of a triangle are 60,45and 75.the shortest side is 10cm less than the longest side, determine the perimeter of the triangle to the nearest cm. include a diagram please and thank you!!

Step-by-step explanation:

We know that the permiter is defined as

Where is the longest side, is the smallest and is the middle side.

If then, , where we need to find an expression for using the law of cosines.

Replacing all expression, the perimeter is

Using a calculator, the perimeter is 20 units centimeters.

do i do it on a graph?

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
