Next, you are going to use the "keep, change, change" method. If you don't know what it means you are basically going to keep the first number the same, change the sign to subtraction, and finally change the negative number into a positive number.
13+-3
13-3
10
You are still getting the same results even if you didn't use this method.

The given Angles (4x + 2) and (3x + 3) are forming linear pair, so

$4x + 2 + 3x + 3 = 180$

$7x + 5 = 180$

$7x = 180 - 5$

$7x = 175$

$x = \dfrac{175}{7}$

$x = 25$

now, let's find Angle DCB :

$3x + 3$

$(3 \times 25) + 3$

$75 + 3$

$78 \degree$

HELP ME THIS IS SO CONFUSING

Harrizon [31]

Answer:

365 degrees :)

Step-by-step explanation:

It's a multiple of 5, but with no zeros, so that means the ones place is 5. The hundreds place is two less than 5, so that's 3. And the tens place is two times the 3, so that gives you 365!

NARA [144]

Answer: 6/11

Step-by-step explanation:

28 - 7 = 21

16 + 11 - 21 = 6

11 - 6 = 5

16-6 = 10

10 + 5 15

P (a) = 16/28

p (b) = 11/28

A I B = 6/28/11/28 = 6/11
