Question

one of the exterior angles of a triangle is 105° and the interior opposite angles in the ratio 2:5. Find the angles of the triangle​

Answer 1

Answer:

Exterior angle = 105 degree.

We know that exterior angle is

equal to sum of two interior opposite angles.

so,

105 = 2x + 5x

105 = 7x

x = 15

so that two angles are:_

75 degree and 30 degree.

Hope it helps.

Answer 2

Answer:

let the two interior angles be 2x an

d 5x respectively

Step-by-step explanation:

So According to question

2x+5x=105(sum of opposite interior angles is equal to exterior one)

7x=105

x=105 /7

x=15
