20 points! answer asap! which statement is true about angles 1 and 2? (image below)
a. they are adjacent angles
b. they are complementary angles
c. they are supplementary angles.
d. they are vertical angles.

A. They are adjacent angles

Step-by-step explanation:

Angles 1 and 2 are next to each other, that makes them adjacent angles

A They are adjacent angles    (next to each other and share a side) True

B. They are complementary angles   (add to 90 degrees)  False-  Angle 2 is 90 degrees)

C. They are supplementary angles.  (add to 180) False, they do not form a straight line

D. They are vertical angles.  (opposite angles)  False, they are not made by intersecting lines

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
