Answer:
<em>120°, 120°, 60°, 60°</em>
Step-by-step explanation:
m∠1 = 180° - 60° = 120°
m∠1 = m ∠2 (alternate interior)
m∠3 = 60° (vertical to given angle)
m∠4 = m∠3 (alternate exterior)
1/12
t-19/7
Multiply the entire expression by 7
7t -133
7t = 133
133/7 = 19
t = 19
0.68 = 0.6 + .08 = 6 x 0.1 + 8 x .01
They should all equal 0.68 :)
