Question

Help me out please simple

Answer 1

A straight line is 180 degrees in measure

The straight line is made up of three angles

--> angle 1

--> angle 2

--> angle with a little square on it

(angle with a little square means it is 90 degrees in measure)

Let's set up an equation

`angle1 + angle2 + 90 = 180\\angle1 + 87 + 90 = 180\\angle1 = 3`

Thus angle 1 is 3 degrees or the second choice

Hope that helps!
