Answer:
Mark still owes $24
Step-by-step explanation:
53-29=24
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:
b = 3c
B = 4c
Step-by-step explanation:
2b + B = 8c
B - b = 2c
_____________ (-)
2b + B - B + b = 8c - 2c
3b = 6c
b = 6c : 3
b = 2c
B = 2c + b
= 2c + 2c
= 4c
It would be A that amy is 8 and billy is 14
9/18 bc 3/6=0.5 and so is 9/18=0.5
