Answer:
t =5
Step-by-step explanation:
2-16t=6(-3t+2)
Distribute
2-16t = -18t +12
Add 18t to each side
2-16t+18t = -18t+18t +12
2 +2t = 12
Subtract 2 from each side
2-2 +2t = 12-2
2t =10
Divide each side by 2
2t/2 =10/2
t =5
Short Answer Only B is true.
Reasoning
A
A is not True. CBG is not equal to DBG. They are supplementary but not equal.
B
B is correct.
C
CBG = DBF are given as equal. It is not necessarily true that they are supplementary. That would be true only if they were both 90o
D
The two angles are equal, but they are not supplementary. They would be only if both were 90o which is shown not to be the case.
Answer:
x = 12
Step-by-step explanation:
We will label the unknown interior angle of the triangle d.
14x - 19 + d = 180
14x + d = 199
d = 199 - 14x
199 - 14x + 3x + 9x + 7 - 2 = 180
199 - 2x +5 = 180
204 - 2x = 180
204 = 180 + 2x
2x = 24
x = 12
