Question

Figure abcd is parallelogram. What are measures of B and D?

Answer 1

Both are 55

Explanation:

To solve this problem, set the equations equal to each other, solve for n, then plug in the values

Solve for n:

1. 2n+15=3n-5

2. Add 5 to both sides

3. Now you have 2n+20=3n

4. Subtract 2n from both sides

5. You are left with n=20

Next, plug it in:

1. Replace all n's with 20

2. 2(20)+15=55

3. 3(20)-5=55

There you go! Hope this helps!
