Answer:
Step-by-step explanation:
Nala's marbles = n
Paul's marbles = 3n
nala loses 5 marbles
so nala's marbles = n - 5
paul buys 10 marbles
so paul's marbles = 3n + 10
Total marbles = 105
so,
n - 5 + 3n + 10 = 105
By transposing,
n + 3n = 105 - 10 + 5
4n = 100
n = 100 / 4
n = 25

Answer: angle 2 is 28
Step-by-step explanation:if angle (1) and (2) are supplementary which equals 180degrees; we know angle one is 152 degrees, so a simple 180-152= 28 degrees; so angle 2 is 28
If you take 180-90 because of the right angle would be 90° then -15 you will get 75 which will be X
