Answer:
x = 24
Step-by-step explanation:
1/6 x + 3 = 7
1/6 x = 4
x = 24
Assuming that the figure is implying that angles 1 and 2 are the same, we have

So, the measure of angles 1 is

Answer:
x= -5/3 y-5
Step-by-step explanation:
Answer:

Step-by-step explanation:
We have:

First, subtract 21 from both sides:

Now, we can complete the square. We will divide the coefficient of the b term and square it. So:

So, we will add 25 to both sides:

The left is the perfect square trinomial pattern. Add on the right:

Final step:
