Answer:
Since BD bisects Angle ABC, Angle ABD = Angle DBC
Subtract 6 from both sides:
Subtract 7x from both sides:
Divide both sides by -4:
Angle
Angle
Angle
9x-7= 29
9x-7+7= 29+7
9x= 36
Divide by 9 for 9x and 36
9x/9= 36/9
x= 4
Check answer by using substitution method
9x-7= 29
9(4)-7=29
36-7= 29
29= 29
Answer is x=4 (second choice)
Answer:
1.19
Step-by-step explanation:
1) Shift the decimals of both 0.8449 and 0.71 to the right by 2 decimal places. (This is needed to convert 0.71 to 71, since long division must divide by a whole number.)
84.49 ÷ 71
2) Use the algorithm method.
1 . 1 9
7 1 | 8 4 . 4 9
7 1 .
1 3 . 4
7 . 1
6 . 3 9
6 . 3 9
3) Therefore, 0.8449 ÷ 0.71 = 1.19.

Answer:
100 degrees
Step-by-step explanation:
A straight line pretty much means you have 180 degrees.
180 - 115 = 65
A triangle has 180 degrees
x = 180 - 15 - 65 = 100
