70°
110°
40°

Imagine you have this triangle

|dw:1419146400509:dw|

jim_thompson5910 · Answer

If you were to translate it to the right for instance, you would get

|dw:1419146428671:dw|

jim_thompson5910 · Answer

Everything about the triangle remains the same: the side lengths, the area, the angles, etc

it's just in a new place. So we have the same shape and figure more or less

jim_thompson5910 · Answer

making sense?

bia_gonzalex · Answer

so the answer is 110?

jim_thompson5910 · Answer

yeah, angle A stays the same because translations preserve (ie keep the same) angle measurements
