Question

The angles of a triangle are in the ratio 5:3:7 The triangle is

(a) an acute angles triangle
(b) an obtuse angled triangle
(c) a right triangle
(d) an isosceles triangle​

Answer 1

Answer:

Acute angled triangle (a)

Step-by-step explanation:

Let angles are 5x,3x,7x

According to question

5x+3x+7x = 180 ( a. s. p)

15x = 180

x = 12

1st angle - 5*12 = 60

2nd angle - 3*12 = 36

3rd angle - 7*12 = 84

All these angles are less than 90 degree so this is an actue angled triangle .

Answer 2

Answer:

option:A

Step-by-step explanation:

• 5X+3X+7X=180
• 15X=180
• X=12
• Angles:60, 30,84
