Answer:
Explanation:
Hi, Danna, these are tough to figure out...
so, first check to see if the 3 known angles add up to 180°, they don't I checked, so, it tells us that the one angle 96° up at the top, does not include ∠2 , which is good, b/c we now know 2 of the angles in that inner triangle.. and we know that a triangle adds up to 180° , so just find that last angle... the one opposite to ∠1 .... nice, if we get the ∠1' angle we can then also figure out ∠1
180-96-30=54
∠1' =54°
so ∠1= 180-54 =126°
we now know ∠1
use that , and that the next smaller triangle also adds up to 180
to find ∠2
∠2= 180-28-126=26°
∠1=126°
∠2 = 26°
:) it's tough to think all of that through. don't worry. just keep working these , they will get easier.
