Answer:
47 degrees
Step-by-step explanation:
The two angles shown are "vertical angles" and thus are equal.
Thus, 2x + 3 = x + 50
Combining like terms, we get:
x = 47 degrees
Answer:
143degrees
Step-by-step explanation:
sum of angles of a triangle =180degrees
let the third unknown angle be x
99+37+x=180
136+x=180
x=180-136
x=44
the sum of two opposite interior angles is equal to the exterior angle
44+99=<PQR
<PQR=143 degrees.
OR
the sum of angles on a straight line is 180 degrees
<PQR+37=180
<PQR=180-37
<PQR=143
Answer:
A
Step-by-step explanation:
A shows a counterclockwise 90° rotation, so it is the correct answer.
B shows a reflection.
C shows a translation.
Hey there! I'm happy to help!
Let's plug in our x value.
-3(6)+9y=18
-18+9y=18
We add 18 to both sides.
9y=36
We divide both sides by 9.
y=4
Have a wonderful day! :D
