This is as close as it can be considering that the picture is a bit blurry. It should be almost exact, but your teacher might want you to round up.
3h+18 is the correct answer:)
Answer:
see explanation
Step-by-step explanation:
(1)
CD = CE - DE = 8 - 2 = 6
CB = CD = 6 ( given as congruent ) , thus
AC = AB + CB = 4 + 6 = 10
(2)
∠ 2 + ∠ BCD + ∠ DCF = 180° ( sum of angles on a straight line )
∠ 2 + 60° + 70° = 180°
∠ 2 + 130° = 180° ( subtract 130° from both sides )
∠ 2 = 50°
So the first thing we need to do is multiply 3*-5, since order of operations dictates it (PEMDAS)
Now, whenever we see a minus negative number, we can think of it as adding a positive number
Now we just add them together
23 is the answer
