Question

The three angles of a triangle are (x-10),(x-20)and(x-30) . Find the measure of smallest angle of the angle

Answer 1

Answer:

By Angle Sum Property, the sum of angles in a traingle sums upto 180 degrees

Therefore,

(x-10) +(x-20) +(x-30) = 180

3x-60 = 180

3x = 180+60

3x = 240

x = 240/3

x = 80

Now, According to the Question, the smallest angle is (x-10)

Therefore, 80 - 10 = 70 degrees

Thus, the measure of the smallest angle is 70 degrees
