Question

One of the exterior angles of a triangle is 153" and the interior opposite angles are in the ratio 5 : 4 Find the three interior angles of the triangle ​

Answer 1

Answer:

here is our answer......

Answer 2

Answer:

85°, 68°, 27°

Step-by-step explanation:

Exterior angle=153°

Opposite interior angle are in the ratio=5:4

=Exterior angle= sume of opposite interior angle

153°=5x+4x=9x

9x=153°

x=153/9

=17°

= One angle=5×17= 85°

= Second angle= 4×17= 68°

=Third angle= x

= Sum of all angles in a triangle= 180°

= 85°+68°+x = 180°

153°+x = 180°

x = 180-153

x = 27°

-- THE THREE ANGLES ARE = 85°, 68°, and 27° .
