Answer:61 degrees.
Step-by-step explanation: If you look at Line MN you will see 103 degrees on the left side. A line is 180 degrees so 180-103=77. Angle P is corresponding with the angle above. Becuase you want to find 2, you have to subtract 77 by 16 to get 61 degrees
5(a-1) - 15 = 3(a+2) + 4
Open all parenthesis and distribute
5a - 5 - 15 = 3a + 6 + 4
Simplify
5a - 20 = 3a + 10
Add both sides by 20 and subtract both sides by 3a
2a = 30
a = 15
Answer:
15.78947% increase
Step-by-step explanation:
First: work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100
The reason for statement 4 is CPCTC.
