4 texts because 18 dollars for 72 texts
can reduce to 1 dollar for 4 texts. i can try to explain further if needed
Subtract 5y from both sides of the equation
X=13-5y
let the other angle be x degree
bigger angle = x +36°
According to the question,
x+36° + x° = 180°
=> 2x = 180–36
=> x = 144/2
=> x = 72°
Measure of the bigger angle = x + 36
= 72° + 36°
= 108°
