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°
The answer would be D because they multiplied the 3 to the other side to get rid of the fraction.
Answer:
Step-by-step explanation:
If the speed is constant for 5 machines and produces x amount of toys we know that rate is defined as a constant per time:
Here the machines are constant and the rate is x toys per hour:
If 5 machines make x per hour:
Rate is x/1 hour
The the ratio of 8/5 is 1.6. Therefore for 8 machines the rate is 1.6 times more per hour than for5 machines. Therefore we can write an expression as:
Rate for 5 machines is x and for 8 machines is y:
