I don't know about the first one but the second one is 34.9°. It would be that because are right angles add up to 90° and if you subract 55.1 and 90 it would equal 34.9. But this rule only works on right angles.
Answer:
x = 5/2
Step-by-step explanation:
So firstly, you want to distribute. It'll make your life much easier.
-2x + 8 = 3
-2x = -5 (subtracting 8 from both sides)
x = 5/2 (dividing both sides by -2 to obtain x)
Hope this helps :)
