Question

find the value of x ​

Answer 1

Answer:

x=130°

Step-by-step explanation:

let the base angles be y

so y+y+80=180 (angle sun property)

so 2y=100

therefore y=50

now x+y=180 (linear pair or angkes in a straight line)

so x= 180-50

x=130

Answer 2

Answer:

x+x+80°=180°

2x+80°=180°

2x=180°-80°=100°

100°/2

50°.

exterior x=50°+50°=100°
