Question

one exterior angle of a triangle is 60 degree. the ratio of two interior angle 2:3. find all the interior angle of the triangle

Answer 1

Answer:

24,36and 120

Step-by-step explanation:

120+2x+3x=180

5x=180-120

5x=60

x=60/5

x=12

we should then substitute x

3x=3(12)=36

2x=2(12)=24

Answer 2

One exterior triangle =60°

Ratio of 2 triangles = 2:3 - - - - - - > 2x and 3x

Orher side of triangle = y

(Exterior angle = sum of opposite interior angles)

Now;

2X + 3X= 60°

5X = 60°

X=12

2X= 2(12) - - - - - -> 24°

3X= 3(12)-------------> 36°

Sum of triangle = 180°

24+36+y =180°

Y=180-60

Y=120°

Hope this helps:-)
