Answer:
c = b- d/a
Step-by-step explanation:
a ( b - c) = d
Divide each side by a
a/a ( b - c) = d/a
b-c = d/a
Subtract b from each side
b-c-b = d/a -b
-c = d/a -b
Multiply each side by -1
c = -d/a +b
c = b- d/a
y = 115
x = 78
The angles in each line have to add up to 180. In this case, it doesn't show the other side of the angle, but you could probably think of it.
Answer:
ABX is 112 degrees.
CBX is 68 degrees.
Step-by-step explanation:
Angles on a straight line always add up to 180 degrees.
Thus,
Remove brackets:
Add up the terms:
Subtract 78 from both sides:
Divide both sides by 34:
Angle ABX
Angle CBX
Answer:
13
Step-by-step explanation:
there is a rule that says that if you add any 2 sides, it should be more than the third. 9+21 is greater than 13. 21+13 is greater than 9. 13 is the only number which if you add 9 to it it will be greater than 21. 12 will equal 21, but it still wont work.
hope this helps :))
