The pentagon has a sum of interior angles of 540 degrees.
Therefore,
(4x + 5) + (5x - 5) + (6x + 10) + (4x + 10) + 7x = 540;
26x = 520;
x = 20;
<span> log3x − 5 16 = 2
+516 +516
log3x=518
x=(10^518)/3
the answer seems a bit crazy, you probably typed something wrong</span>
Answer:
thanks!
Step-by-step explanation:
(2y + 5)° = 4y °
- 4y + 2y° = -5°
-2y° = -5°
y =5/2
