Answer: ∠P= 20°
<h3>
Step-by-step explanation: Well we know that the sum of a triangle always equals to 180°, so ∠P + 80 +80 = 180°
</h3>
∠P + 160 = 180
Subtract 160 from both sides, 160 on the left is cancelled so that 180-160 equals 20
∠P=20°
Answer: 55
The angles that measures 125 and y make a linear pair (equal 180)
So you just do 180-125 to get y

The applicable rules of logarithms are ...
log(ab) = log(a) +log(b)
log(a/b) = log(a) -log(b)
log(a^b) = b·log(a)
