Amy can estimate with 10% instead, so she can just simply move the decimal point of $9.11 to the right, and so it will be estimated to more than 91 cents.
Answer: A. (x - 4, y - 2)
B. (x + 7, y - 11)
<u>Step-by-step explanation:</u>
A) How do you get the x-coordinate of 3 to become a x-coordinate of -1? by subtracting 4 --> x - 4
How do you get the y-coordinate of 5 to become a y-coordinate of 3? by subtracting 2 --> y - 2
The transformation is: (x - 4, y - 2)
B) How do you get the x-coordinate of -4 to become an x-coordinate of 3? by adding 7 --> x + 7
How do you get the y-coordinate of 11 to become a y-coordinate of 0? by subtracting 11 --> y - 11
The transformation is: (x + 7, y - 11)
The base angles are both 74°
Further explanation:
An isosceles triangle is a type of triangle that has two sides and two angles equal.
Let A, B and C be three angles
Let A=32°
If A is 32 then B and C will be equal
The internal angles of a triangle are 180°
So,
m∠A+m∠B+m∠C=180°
We know that B and C are equal
m∠B=m∠C
So putting the value of A and replacing C by B
32°+m∠B+m∠B=180°
32°+2m∠B=180°
2m∠B=180°-32°
2m∠B=148°
m∠B=148°/2
m∠B=74°
As
m∠B=m∠C
So
m∠C=74°
The base angles are both 74°
