Question

if three angles of triangle is 1 to 2 is to 1 find the greatest angle​

Answer 1

$</p><p>\huge\red{\bold{ANSWER:}}$

angles ratio = 1:2:1

let the angles be 1x, 2x, 1x

we know that angle sum = 180°

now,

1x + 2x + 1x = 180

4x = 180

x = 45°

now the angles are 1x, 2x, 1x that are (45°) , (2 × 45°= 90°) , (45°)

hence, greatest angle is 90°

Answer 2

Answer:

90 degree

Step-by-step explanation:

lets take the three angles as 1x +2x +1x =180 degree

                                                   4x = 180 degree

                                                    x = 180/4

                                                      = 45 degree

so the three angles of the triangle are 1 x 45 =45 degree

                                                                   2 x 45 =90 degree

                                                                   1 x 45 =45 degree

Therefore the greatest angle of this triangle is 90 degree.
