Question

3. One of the exterior angles of a triangle is 100° and its interior opposite angles are equal to each other.
What is the measure of each of these two angles ?
4. One of the exterior angles of a triangle is 130° and the interior opposite angles are in the ratio 2:3
find the angles of the triangle​

Answer 1

Answer:

Step-by-step explanation:

Let each interior angle be x

Sum of interior angles = exterior angle of a triangle

x+x=100

2x=100

x=100/2

x=50

Let the smaller interior angle be 2x

Let the larger interior angle be 3x

Sum of interior angles = interior Angle of a triangle

2x+3x=130

5x=130

x=130/5

x=26

Smaller angle = 2x = 52

Larger angle = 3x = 78
