The Answer is D
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>
-1, 0.5, 2/3, 1.1 is the order of the numbers from least to greatest
It would be -2z+8. Because 3z+-5 is -2 and 2+6 is 8.
