Answer:
well this is the answer
Step-by-step explanation:
You need the Law of Cosines here and you use it when you have 2 sides and an enclosed angle. The side across from the angle is the one we are looking for. The correct way to express the Law using what we have is the last choice above. Side RT is the unknown, and it is across from the angle that is enclosed between the 2 other sides.
Solve each equation with (0, 3)
y = -x + 3
3 = -0 + 3
y = 3 (correct since y = 3 in (0, 3))
y = 2x - 3
3 = 2(0) - 3
3 = 0 - 3
3 = -3 (incorrect since it isn't equal)
So... No, because it does not check in the second equation.
Best of Luck!
Answer:
61
Step-by-step explanation:
84+38=122
180-122=58
DBC=58
180-58=122
122÷2=61
61+58=119
180-119=61
Anything that adds up to 12 has to go in the parethese.
48 / 4 = 12
So 1 and 11
2 and 10
3 and 9
4 and 8
5 and 7
or
6 and 6
