Question

the angles of a triangle are in the ratio of 5:3:7, the find the type if given triangle.

step by step explanation​

Answer 1

Answer:

Let the angles are 5x, 3x, 7x.

so,

$5x + 3x + 7x = 180 \\ 15x = 180 \\ x = \frac{180}{15} = 12$

so angles are 60, 36, 84.

Here all angles are unequal & acute so triangle is

Acute Scalene triangle.
