Answer:
The angles labeled in the picture are both 25.
Step-by-step explanation:
It says that both are equal in measure, so you can write an equation to find x. The equation would be x+21=7x-3. To solve that, combine like terms. The answer to the equation is x=4. The work to solve that is...
x+21=7x-3
x+24=7x
24=6x
4=x
Then substitute each x for 4. The equation would look like...
4+21=7(4)-3
Each side of the problem would equal to 25. That means both angles measure as 25.
