Given
Reflection across y-axis
Required
Coordinates of C'
When a point is reflected across the y-axis, the rule is:
So, the reflection on C will be:
Answer:
Step-by-step explanation:
Plug in the given value of y, -2, and solve for x:
-2 + 2 = -3x + 4 and
0 = -3x + 4 and
-4 = -3x so
x = 4/3
Answer:
27.92 units
Step-by-step explanation:
Radius (qr) = r = 16 units
<QŘS = θ = 82°
Length of an arc = (Θ / 360) * 2πr
L = (θ / 360) *2πr
L = (82 / 360) * 2π * 16
L = 0.2777 * 100.53
L = 27.917 units
L = 27.92 unit
Answer:
m∠3 = 56
Step-by-step explanation:
Let's solve for x, first:
x + 9 = 3x - 85
9 = 2x - 85
94 = 2x
94/2 = x
47 = x
Now that we have x-value, we can substitute it in any one of the given equation to find angle 3 since, angle 1, 7 and 3 all are congruent:
=> m∠7 = x + 9
=> m∠7 = 47 + 9
=> m∠7 = 56
Since m∠7 ≅ m∠3
and m∠7 = 56, then
<u>m∠3 = 56</u>
Hope this helps!
