one of the exterior angleof triangle is 135⁰ and the interior opposite angles are in the ratio of 4:5 and the angles are About the author Serenity
Step-by-step explanation: property to be used: the sum of two angles of a triangle is equal to the exterior ange of the third angle of the same triangle. given ratio = 4:5 the sum of given angles= 135° let 4x be La let 5x be Lb hence, 4x+5x= 135 9x= 135 x=15 therefore, the angles are: La=4x =4(15)= 60° Lb=5x=5(15)= 75° i hope this helps. plz mark me as the brainliest.

Step-by-step explanation:
property to be used:
the sum of two angles of a triangle is equal to the exterior ange of the third angle of the same triangle.
given ratio = 4:5
the sum of given angles= 135°
let 4x be La
let 5x be Lb
hence, 4x+5x= 135
9x= 135
x=15
therefore, the angles are: La=4x =4(15)= 60°
Lb=5x=5(15)= 75°
i hope this helps.
