The longest side of a triangle is 5 inches. Longer than the shortest side. The medium side is 4 inches. Longer than the shortest
Llana [10]

Answer:

The answer to your question is L = 10 in , M = 9 in ; S = 5 in

Step-by-step explanation:

Data

longest side = 5 + x in

medium side = 4 + x in

shortest side = x

Perimeter = 24 in

Process

1.- Write and equation to solve this problem

    Perimeter = longest side + medium side + shortest side

Substitution

             24 = (5 + x) + (4 + x) + x

Simplification

            24 = 5 + x + 4 + x + x

            24 = 9 + 3x

            24 - 9 = 3x

                  15 = 3x

                   x = 15/3

                   x = 5

2.- Calculate the lengths of the side

Longest side = 5 + 5 = 10 in

Medium side = 5 + 4 = 9 in

Shortest side = 5 in

Find the missing angles for each problem, given that lines a and b are parallel (step by step)
hodyreva [135]

STEP BY STEP EXPLANATION:

4=86⁰ because the lines are parallel.

49⁰+86⁰=180

135=180

180-135

45

5=45⁰

2=49⁰ BECAUSE THE LINES ARE PARALLEL

NOW FOR ANGLE 1

45+86

131

as A & B ARE PARALLEL SO

Nezavi [6.7K]

Let the first number = x

The second number would be 5x

The third number would be 100x

Add:

X + 5x + 100+x = 296

Simplify:

7x + 100 = 296

subtract 100 from both sides:

7x = 196

Divide both sides by 7

X = 196 / 7

X = 28

First number is 28

Second number is 28 x 5 = 140

Third number = 128
