Question

2. If the largest angle formed in triangle is 70°, then what is the least possible value of the smallest angle of triangle ?
A) 30° B)50° C)10° D)40°​

Answer 1

Answer:

B) 50°

Step-by-step explanation:

the total angle of triangle = 180°

70° + x + y =180

x +y = 180- 70 = 110 °

x +y = 110°

from the question, we can say that the largest angle is 70° and other angles i.e x and y are less than 70°

• so, if smallest angle is 30° then the other will be 80°

       if we do so then the largest angle is 80°, not 70

• if the smallest angle is 50° then the other will be of 60°    

so the angles of the triangle are 70°,50°and 60°
