Question

solve this sum fast​

Answer 1

Answer:

Hence, the angles are 30,75,75 degree

Step-by-step explanation:

Given, the interior opposite angles to the exterior angle 105∘ are in the ration 2:5

∴2x+5x=105 degree

7x=105o ⟹x=15 degree

Therefore the interior opposite angles to the angle 105o are 2x=2(15)=30o and 5x=5(15)=75 degree

Let the third angle of the triangle be C

Let the third angle of the triangle be CWe have the sum of interior angles of a triangle is 180.

∴30o+75o+C=180

C=180o−75o−30o=180o−105

C=75

Hence, the angles are 30,75,75.
