if three angles of triangle is 1 to 2 is to 1 find the greatest angle
Answers
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:
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.
