ALR SO, GET READY,

We see angle 120, 1 looks like an opposite of 120 so the answer for 1 is 120

- so 120 is corresponding to the angle supplementary to 2. SO, 180 (the sum of the angle) minus 120 is 60 I THINK so 2 is 60

SO 3 again we know 2 is 60 and the angle opposite to 2 is also 60 so then we say what number is supplementary to 60… its 120 so 3 is 120

Answer’s:
1=120
2=60
3=120

Answer:

Explanation:

We can easily find 1, because 1 is a vertical angle to 112. That means that angle 1 is 112°

next we find #3. since there are parallel lines, 1 and 3 are equal due to them being corresponding angles. so angle 3 is 112°

now since there is a straight line, the sum of angle 2 and angle 3 should be 180. Since we know what angle 3 equals, we have to do some simple math.

112 + x = 180

x = 68

so angle #2 is 68° because angle 2 & 3 are supplementary.
