Answer:
these are supplementary
and x = 50
Step-by-step explanation:
one straight line = 180 degrees
there are only two angles making up this 180 degree line, so by definition they are supplementary
76 + 2x + 4 = 180
80 + 2x = 180
2x = 100
x = 50
Answer:
Value : c = ad - b
Step-by-step explanation:
Given the equation: Solve for c;
Multiply both sides by d in we get;
subtract b from both sides we have;
Simplify:
ad - b = c
Therefore, the value of c is, ad -b
