let the exterior angle be x
x=60°+80°(being one exterior angle is equal to two interior angle)
x°=140°
Answer:
8/5
Step-by-step explanation:
6x
Step-by-step explanation:
1.2(4x-1)=8x-2=6x
1012 divided by 120 is 8.43 so 9 boxes will be needed
Answer:
ASA
Step-by-step explanation:
Triangle ABD is congruent to triangle BDC by ASA because angle B in ABD is 30 degrees. Then they give you BD which equals BD by the reflexive property. And finally angle D in ABD is also 30 degrees. In triangle BCD, angle B is 30 degrees, BD = BD, and angle D in BCD is 30 degress. So we have an angle (B), side (BD), and another angle (D)
