<u>A straight line is 180 degrees in measure</u>
<u>The straight line is made up of three angles</u>
--> angle 1
--> angle 2
--> angle with a little square on it
(<em>angle with a little square means it is 90 degrees in measure)</em>
<u>Let's set up an equation</u>
Thus angle 1 is <u>3 degrees</u> or the <u>second choice</u>
<u></u>
Hope that helps!
if you make a graph and add the coordinates on the graph you can use that find out how it creates a ratio of 1:2
X + 7x = 56 + 8
Simplifying x + 7x = 56 + 8 Combine like terms: x + 7x = 8x 8x = 56 + 8 Combine like terms: 56 + 8 = 64 8x = 64 Solving 8x = 64 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Divide each side by '8'. x = 8 Simplifying x = 8
