Answer:
I think its flat sorry if it's wrong
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>
Answer:
-5/6
Step-by-step explanation:
We are given two points, so we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -2 -8)/(20 -8)
-10/12
-5/6
I dont understand the first ques !!
But
2) Only a is correct
3)Only b is correct
4) Both a and b are correct !!
