For number 9 it's x+8= 14 and 7x=21
For number 10 the answer is that Beth is correct because the only number that could be replaced for x would be 2. There is no number besides 2 that you could put in the equation x+3=5 to get the answer 5.
If angle 1 and angle 2 are <u>complementary, </u>then they add up to 90 degrees. We are given that angle 2 equals 52 degrees.
So we subtract and get our answer:
38
That's NOT the final answer.
The next step is:
Angle 1 and angle 3 are vertical angles.
Vertical angles are congruent.
So if angle 1 is 38, then angle 3 is also 38.
Now, supplementary angles add up to 180 degrees.
So that's the answer:
180-38=142
142 is the supplement of angle 3.
Hope it helps! :)

do you still need help with this?
Step-by-step explanation:
because I can help. just comment back to me
ABCD is a parallelogram ⇒ BE = DE
So: 7x - 12 = 3x + 4
⇔ 7x - 3x = 4 + 12
⇔ 4x = 16
⇔ x = 16/4 = 4
⇒ BE = 7(4) - 12 = 28 - 12 = 16
⇒ DE = 3(4) + 4 = 12 + 4 = 16
⇒ BD = BE + DE = 16 + 16 = 32
Answer: BD = 32
Ok done. Thank to me :>
