Question

In the given figure,find the measure of <A A ​

Answer 1

Answer:

exterior angle in triangle=sum of opposite interior angles in a triangle

130=60+<A

<A=130-60

<A=70

Answer 2

Answer:

70 degrees

Step-by-step explanation:

1. the rule is sum of opposite interior angles is equal to exterior angle..
2. so take angle A as x..
3. then angle A + 60 degrees=130degrees
4. we got x+60 degrees=130 degrees
5. send 60 degrees to right side
6. then we got x=130 degrees -60 degree
7. then the answer is 70 degrees
