Step-by-step explanation:
The angles of triangle = 5x,3x and 7x
We know Sum of all angles of triangle= 180°
5x + 3x + 7x = 180°
15x = 180°
x= 180/15
x= 12°
hence, 5x = 5× 12 = 60°
3x= 3×12 = 36°
7x = 7×12 = 84°

Answer:
HOPE IT HELPS MARK BRAINLIEST!!!!!
Step-by-step explanation:
The angles of the triangle are in the ratio: 5:3:7
Let the angles be 5x,3x,7x
By Angle sum property,
5x+3x+7x=180
15x=180
x=12
Thus, angles are, 60°,36°,84°
Since, all the angles are less than 90°, it is an acute angled triangle.
