Answer 1

Answer:

x = 80°

Step-by-step explanation:

✔️We know that,

• ABCD is a quadrilateral (has four sides)

• A and B are adjacent angles. (next to next or just beside each other)

In a quadrilateral,

sum of adjacent anglez is equal to 180°

Then we can write,

➡️(x-10)+(x+30) = 180°

➡️x-10+x+30 = 180°

➡️ 2x +20 = 180°

➡️ 2x = 180-20

➡️ x= 160/2

➡️ x= 80°
