4. The angles of the triangle are in the ration 2:3:4. Find them.
Answers
Answer:
then angle of triangle are =2x=40⁰
=3x=60⁰
=4x=80⁰
The angles of triangle are 40, 60 and 80
Step-by-step explanation:
It is given that the angle of triangle are in the ratio 2 : 3 : 4. Let the angles are 2x, 3x and 4x.
According to the angle sum property, the sum of interior angles of a triangle is 180 degree.
2x+3x+4x=1802x+3x+4x=180
9x=1809x=180
x=20x=20
The value of x is 20.
2x=2(20)=402x=2(20)=40
3x=3(20)=603x=3(20)=60
4x=4(20)=804x=4(20)=80
Therefore the angles of triangle are 40, 60 and 80.
Answer:
40°, 60° and 80°
Step-by-step explanation:
Let the given angles of the triangle be 2x, 3x and 4x.
We know that,
Sum of all angles of a triangle = 180°
2x+3x+4x = 180°
9x = 180°
x = 180°/9
x = 20°
The angles are,
2x = 2(20°) = 40°
3x = 3(20°) = 60°
4x = 4(20°) = 80°
Therefore, the values of the angles of the triangle are 40°, 60° and 80°.
Hope it helps you.
Good Luck.
