Pi is just 3.14--- math questions will most likely ask you to round to the nearest tenth or something of the sort -
-2 negative 2 is the answer
A) Two parallel lines, intersecting a 3rd line (a traversal), indicates that two same-sided, internal angles MUST be SUPPLEMENTARY (sum, or add up to 180°).
b) Since <1 and <2 are supplementary, they add up to 180°. Therefore, <1 + <2 = 180:
(20x+5) + (24x-1) = 180
44x + 4 = 180
44x + 4 -4 = 180-4
44x = 176
44x/44 = 176/44
x = 4
Recall that like terms are terms that have the same variable with the same exponent, and that all constants are like terms.
To solve the given equation for y, first, we add like terms:

Now, adding 1.6 to both sides of the equation, we get:
