Answer:
b is 10 degrees and a is 64 degrees.
Step-by-step explanation:
Properties of a parallelogram needed for this problem: Opposite angles are congruent and adjacent angles are supplementary, meaning they add to 180 degrees.
This means that in the picture, 2a and 12b+8 are equal, while 2a and 5b+2 are supplementary.
From this we can make two equations:
2a=12b+8
and
2a+5b+2=180
If we subtract 5b+2 in the second equation, both equations will equal 2a. I'll explain why that's good. We end up with:
2a=12b+8
and
2a=180-5b-2
Now, we can set the two equations equal to each other because they both equal the same thing. Then simplify.
12b+8=180-5b-2
17b=170
b=10
Knowing b is 10 degrees, we can easily plug that back into one of our original two equations. I'll choose 2a=12b+8.
2a=12(10)+8
2a=120+8
2a=128
a=64
b is 10 degrees and a is 64 degrees.

/3
b+9
Step-by-step explanation:
Let's solve for <em>b</em>.
50b+3f=27
Step 1: Add -3f to both sides.
50b+3f+−3f=27+−3f
50b=−3f+27
Step 2: Divide both sides by 50.
50b
/50
=
−3f+27

Let's solve for <em>f</em>.
50b+3f=27
Step 1: Add -50b to both sides.
50b+3f+−50b=27+−50b
3f=−50b+27
Step 2: Divide both sides by 3.
3f

=
−50b+27

Step-by-step explanation:
Answer:
+x=-y
Step-by-step explanation:
It would be 0.2
Because
1 divided by 5 = 0.2
To check
0.2*5=1
