Hey!!!!...Here is the answer
As we know that the sum of the exterior angles of triangle is = 360°
Now,
=> (2x+10)+(3x-5)+(2x+40)=360
=> 7x+45=360
=> 7x=315
=> x= 45°
Now the answer of
(a) Value of x=45°
(b) Smallest interior angle = 180- largest exterior angle
=> 180-(2x+40)
=> 180-130
=> 50°
(c) Largest interior angle = 180- smallest exterior angle
=> 180- (2x+10)
=> 180-100
=> 80°
Hope it will help you ☺

thanks a ton...I'll surely mark as brainliest
:-)
could u please explain me that where did you get 130 from in the b part
and where did you get 100 in the c part
In b part..put the value of x in 2x+40
similarly in part c put the value of x in 2x+10
thanks a lot
n can u solve my other questions... just check my profile thanks
Okk
thanks

❤❤Here is your answer ✌ ✌
(2x+10)° + (3x-5)° +(2x+40)°=360°
7x+45°=360°
7x=360-45
7x=315
x=45°
largest interior angle=180°-(2x+10)°
180°-100
=80°
smallest interior angle=180°-(2x+40)°
180°-130
=50
(2x+10)° + (3x-5)° +(2x+40)°=360°
7x+45°=360°
7x=360-45
7x=315
x=45°
largest interior angle=180°-(2x+10)°
180°-100
=80°
smallest interior angle=180°-(2x+40)°
180°-130
=50
