Question

If two complementary angles are in the ratio 3:2, then the smaller angle is

1 point

. If one angle of the triangle is 60⁰ and other two angles are in the ratio 1:3 ,then the smallest angle

1 point




​

Answer 1

Answer:

Let the two angles be ×

60 degree+1x+3x=180

then,60+4x=180

4x=180-60

4x=120

x=120/4

x=30

So,the value of x is 30

value of ratio= 1x30=30,3x30=90

Hence the smallest angle is 30 degree.
