Question

If the angles of a triangle are in the ratio
of 1:1:4, find all the angles.​

Answer 1

Answer:

1x + 1x + 4x = 180

6x = 180

x = 180/6

x = 30

1x = 30 degrees

1x = 30 degrees

4x = 120 degrees

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

In triangle ABC

angle A + angle B + angle C= 180 [angle sum property of a triangle]

1x + 1x + 4x = 180 [taking the common factor as x]

6x = 180

x = 30

thus,

angle A = 1x = 1*30 = 30

angle B = 1x = 1*30 = 30

angle C = 4x = 4*30 = 120

verification:

angle a + angle b+ angle c

30+30+120

180

hence verified
