2(2-j)= 4 ( j + 10)
Steps:
1. Multiply everything in parentheses
4 + -2j= 4j + 40
2. Add 2j on both sides
4= 6j + 40
3. Subtract 40 on both sides
-36= 6j
4. Divide by 6
5. Your answer is
J= -6

BD is the angle bisector of ABC. Find m ABC and m DBC. (Picture attached!) Thank you!!!

Marrrta [24]

Answer:

60 Degree,30 degree

Step-by-step explanation:

BD is bisector of ∠ABC

=> ∠ABD = ∠DBC

=> 3x = x + 20

=> 3x - x = 20

=> 2x = 20

=> x = 20/2

=> x = 10

Now,

∠ABD = ∠DBC = x + 20 = 10 + 20 = 30 Degree

∠ABC = ∠ABD+∠DBC = 30+30 = 60 Degree

Craig went to see a play at a theater downtown. The first act was 45 minutes long. Intermission lasted for 55 minutes and the se

Digiron [165]

Answer:

The play started at 5:10 PM.

Step-by-step explanation:

We are given the following in the question:

Length of first act = 45 minutes

Length of intermission = 55 minutes

Length of second act = 1 hour and 10 minutes

1 hour = 60 minutes

Thus, length of second act =

$=60+10\\=70\text{ minutes}$

The second part ended at 8:00 PM. We have to find the starting time of play.

Starting time of play =

$= 8-\dfrac{45+55+70}{60}\\=8 - 3\text{ hours} + 10\text{ minute}\\=5:10\text{ PM}$

Thus, the play started at 5:10 PM.
