Question

can someone help me please? whoever knows basically simple geometry could probably help. thanks in advance!

Answer 1

Answer:

Angle 2 = 20°

Step-by-step explanation:

90+70=160

160+20=180

All of the angles inside a triangle will ALWAYS add up to 180°. So, if you have 2 angles already known, just add them together and find out what you need to add to that to get to 180.

Hope this helps! :)
