Ex1) a. supplementary (angle A + angle B gives 180) b. neither c. complementary (angle A + angle B gives 90)
Ex2) An angle of 180° (since it makes a straight line)
Supplementary angles are any angles that give 180 in sum, so for example 90° and 9°
Two different ones could be 150 and 30, for example
2 complementary angles are any angles that give 90 in sum, so for example 45 and 45 or 50 and 40
Since we know that a straight angle is 180 (like in the picture), and we are given (in that straight angle) an angle of 90° (the left) and 55° (CED) we only need to find BEC. Again, since a straight angle gives 180°, we just need to sum all of these and get 180°:
90 + 55 + BEC = 180
145 + BEC = 180
BEC = 180 - 145
BEC = 35°
Answer:
n= -12
Step-by-step explanation:
- 2n/3 + 7=15 Subtract 7 from both sides and move all terms containing
-7 = -7 n to the right
- 2n/3 = 8 multiply both sides of equation by - 3/2
-3/2 x (-2n/3) = -3/2 x 8
n= -3/2 x 8 cancel the common factor of 3
n= -12

Answer:
y-7=x-4
Step-by-step explanation:
If you change the equation to y=mx+b yout would get Y=x+3 plug in the point (4,7) and you would get 7=4+3
7=7 so that is correct.
