Vertical angles are equal
7x - 19 = 4x + 2
7x - 4x = 2 + 19
3x = 21
x = 21/3
x = 7
m∠ABC = 4x + 2 = 4*7 + 2 = 28 + 2 = 30°
Answer:

Step-by-step explanation:
Use the <u>Slope Formula</u> to help you determine the slope of the following two points:

(Where
is the first point and
is the second point)
-Apply both points onto that formula:



-Solve:



<h3>
Answer:</h3>
A. 28
<h3>
Step-by-step explanation:</h3>
We assume m is the measure of the marked unknown angles: ∠BZY ≅ ∠BZA
(5x +3)° = (2x +18)°
Divide by ° and subtract 2x+3:
... 3x = 15
... x = 5
Then ∠BZA = (2·5 +18)° = m = 28°
Answer:
580742.5, in words: five hundred eighty thousand seven hundred forty-two and a half.
Multiply: 1489 * 390 = 580710
Divide: 65 / 2 = 32.5
Add: 580710+32.5 = 580742.5
A, tell me if wrong. Also if it it wrong i am really sorry
