Question

one angle is 30° and second angle is thrice that of the third angle find the measure of all angles

Answer 1

If u r asking for a triangle then,

let the measure of third angle be x°
so, measure of second angle = 3x°
one angle= 30°

Since , the sum of all angles of a triangle is 180°
so, 30° + x° + 3x° = 180°
=>30° + 4x° = 180°
=>4x° =180°-30°
=>4x°=150°
=>x° = 150°/4
=>x° = 37.5
Hence, second angle = 3x = 112.5°
third angle = x° = 37.5°

Answer 2

Answer:

Step-by-step explanation: first angle is 30

Let the third angle be x

Second angle =3x

Applying angle sum property of triangle, 30 + x+ 3x = 180

4x = 150

X = 37.5

So first angle is 30

Second angle is 3*37.5 = 112.5

Third angle is 37.5
