Answer:
Step-by-step explanation:
sum of angles of a triangle= 180°
x+2x+2x+10=180
5x+10=180
5x=170
x=170/5
x=34
.:
x=34°
2x=34×2=68°
2x+10=2×34+10=68+10=78°
Answer:
The correct answer is A. Whether the relative was born in Korea; Whether the relatives speak korean
Step-by-step explanation:
-3(4-2y)=24
Apply distributive property
-12+6y=24
Add 12 to both sides
6y=36
Divide both sides by 6
y=6

Answer: 180 degrees</h3>
note: it doesn't matter if its clockwise or counterclockwise when it comes to 180 degree rotations.
========================================
Explanation:
The rule for 180 degree rotations is
(x,y) ---> (-x, -y)
So the x and y coordinates flip in sign from positive to negative, or vice versa.
Point D ' (-3, 5) rotates to D ' (3, -5) following this rule
-----------------
A further detailed break down might look like this
x = -3 becomes -x = -(-3) = 3
y = 5 becomes -y = -5
(-3, 5) ----> (3, -5)
