Answer 1

Step-by-step explanation:

115°=50°+x

115°-50°=x

65°=x

Answer 2

Answer:

65°

Step-by-step explanation:

Sum of the angels will be 180°

so now,

we will subtract 115° by 180°

180° - 115° = 65°

We take 180° in the equation to find the value of x.

The equation will be:

50° + 65° + x = 180°

115° + x = 180°

x = 180° - 115°

x = 65°
