Question

are in the
(2) The measures of the angles of a triangle
ratio 5:6: 7. Find their measures.
Solution :​

Answer 1

Let 5x,6x and 7x be the angles of a triangle.

By angle sum property, sum of all the angles in a triangle=180

∘

⇒5x+6x+7x=180

∘

⇒18x=180

∘

∴x=

18

180

=10

∘

5x=5×10

∘

=50

∘

6x=6×10

∘

=60

∘

7x=7×10

∘

=70

∘

∴ the angles 50

Answer 2

Answer:

50°, 60° and 70°

Step-by-step explanation:

5x+6x+7x=180°

18x=180°

x=10°

so,

5x=5*10=50°

6x=6*10=60°

7x=7*10=70°
