please help me i need a urgent help please solve this problem please answere me and please answere me on a page​

Answer 1

Required Answer :

• first Angle of triangle = 52°
• Second Angle of triangle = 78°
• Third Angle of triangle = 50°

Given :

• one Exterior angles of triangle = 130°
• interior two opposite angles are in ratio = 2:3

To find :

• All Angels of given triangle.

Some property of triangle will be used in this question are :---

☞ One property of triangle is - Sum of two interior angle of triangle is equal to Measure of one exterior angle.]

☞ One property of triangle is that- Sum of interior angle of triangle is always 180°

Explanation :

• let suppose that two Given interior angle of triangle are => 2x and 3x

• And, third interior angles = y

Hence,

According to the property of triangle which is given above , we can make a equation as :-

• 2x + 3x = 130° ------ ( 1st given property)

=> 5x = 130°

=> x = 130/5

=> x = 26°

Now, we have the value of x.

so, putting the value of x in 2x and 3x.

• 2x

=> 2 × 26°

=> 52°

• 3x

=> 3× 26

=> 78°

So, by this Explanation, we found that two angles of triangle = 52° and 78°

Now,

FINDING THIRD ANGLE :-

By using second Given property of triangle, We have =>

52° + 78° + y = 180°

=> 130° + y = 180°

=> y = 180° - 130°

=> y = 50°

So, third angle of triangle is = 50°

Hence, By this Explanation we found three angles of triangle as ===>

1. 52°
2. 78°
3. 50°
