Question

the ratio of the measure of the sides of a triangle is 21:18:4. if the perimeter of the triangle is 215 feet, find the length of each side the classify by the sides

Answer 1

Answer:

the measure of the sides of the triangle will be

105°,90°, and 20° respectively

let the measure of the triangle be

21x,18x and 4x

we know that

21x+18x+4x=215

43x=215

x=215/43=5

x=5

21(5),18(5), and 4(5)

so then we get

105° 90° and 20°

Answer 2

Step-by-step explanation:

21x + 8x + 14x = 215

43x=215

x=5

21x=21×5=105

8x=8×5=40

14x=14×5=70
