Answer:
angle 1: 43
angle 2: 137
Step-by-step explanation:
Lets find angle 1 first :)
Since oposite diagonal angles are the same, this will make angle 1 43 degrees :)
Now lets find angle 2!
Since 1 was 43 degrees, and a flat line is 180 degrees we must subtract!
Lets do that now!
180 - 43 = 137
Angle 2 will be 137 degrees!
Have an amazing day!!

Answer and Explanation:
m∠1 = 43° because opposite angles are congruent
m∠2 = 137° because ∠2 and 43° are supplementary, so m∠2 + 43° = 180°
m∠3 = 137° because opposite angles are congruent, so m∠3 = m∠2
m∠5 = 43° because alternate angles are congruent
m∠6 = 137° because ∠5 and ∠6 are supplementary, so 43° + m∠6 = 180°
m∠7 = 137° because alternate exterior angles are congruent, so m∠7 = m∠2
m∠8 = 43° because alternate exterior angles are congruent, so m∠8 = m∠1
