im sorry but did you ever get the answer?
Answer:
x=2
Step-by-step explanation:
The angle show with the yellow square has a measure of 90°.
Together with angles 1 and 2, they form a straight angle so we have:
∠1+∠2+90°=180°,
subtracting 90° from both sides we have:
∠1+∠2=90°
If the sum of the measures of 2 angles is 90°, the angles are called complementary.
Since the sum of the measures of angles 1 and 2 is 90°, then these 2 angles are complementary.
Answer: <span>They are complementary</span>
