use a calculator instead of asking
Answer:
statement
the sum of two adjacent angle of a triangle is 180° . prove that sides are parallel.
Add 60+15, divide by 3, subtract 2
E^x^2 - 9 = 1
e^x^2 = 1 + 9 = 10
Ln e^x^2 = Ln 10
x^2 = Ln 10
x = sqrt (Ln 10) = 1.517
x = 1.517
Am not sure but maybe no because i learned it 2 month ago
