Answer: 130</h3>
Explanation:
Let x be the unknown angle we want to find.
Let y be adjacent and supplementary to x. This means x+y = 180
Let z also be adjacent and supplementary to x. So x+z = 180 also
Subtracting the two equations leads to y-z = 0 and y = z. So effectively we've proven the vertical angle theorem.
Since the supplementary angles to x add to 100, we know that y+z = 100. Plug in y = z and solve for z
y+z = 100
z+z = 100
2z = 100
z = 100/2
z = 50
Therefore,
x+z = 180
x+50 = 180
x = 180-50
x = 130
Answer: 1= X = 8
2= X = 6
3= X = 7
4= X= 9/13 or X= 0.692307

Answer:
Therefore first number is 3 and second number is 18
Step-by-step explanation:
Sum of the two numbers is 21 and Second number is six times the first number
x+6x = 21
7x = 21
x = 21/7
x = 3
substitute x value in 6x to find second number,
= 6x
= 6*3
= 18
