Question

Tell whether the angles are adjacent or vertical. Then find the value of $x$ .

Two lines intersect each other forming two pairs of opposite angles. The one pair of opposite angle is labeled left parenthesis x plus 3 right parenthesis degrees and 84 degrees.

Answer 1

they are adjacent angles

Explanation:

for adjacent angles

`{(x + 3)}^(o) = {84}^(0) \\ x = 84 - 3 \\ x = 81`
