Answer:
559,999
Step-by-step explanation:
Opposite angles have the same measure. So, we can set the following equation:
From here, we can forget about the geometry and continue algebraically: subtract 2x from both sides:
Add 52 to both sides:
Answer:
16
Step-by-step explanation:
3/4y-7=5
*multiply both sides of the equation by 4
= 3y-28=20
*move <u>constant</u> to the right-hand side and change its sign
=3y=20+28
*add the numbers <u> </u>
=3y=48
*divide both numbers by 3
and that's how you get 16
