Answer:
The answer is below
Step-by-step explanation:
a) Triangle A is attached in the image below.
The base of triangle A is 3 units and its height is 3 units. The area of a triangle is given as:
Area = (1/2) × base × height
Area of triangle A = (1/2) × base × height = (1/2) × 3 × 3 = 4.5 unit²
Area of the scaled copy = 72 unit²
Ratio of area = Area of the scaled copy / Area of triangle A = 72 unit² / 4.5 unit² = 16
Hence the scaled copy area is 16 times larger than that of triangle A.
b) For the scaled copy:
Area of the scaled copy = (1/2) × base × height = 72 unit²
base × height = 144
Since the base and height are equal
base² = 144
base = 12, also height = 12
Base of scaled copy = 12 = 4 × base of triangle A
Therefore the scale factor used is 4
The answer is B. There can not be any alike "x" inputs.

Step-by-step explanation:
We have been given an image of a circle. We are asked to find the value of each variable.
We can see that angle b corresponds to diameter of circle. We know that the measure of an angle that is inscribed to the diameter of a circle is 90 degrees . Therefore, the value of b will be 90.
we can see that angle is an inscribed angle of arc 99 degrees. We know that measure of an inscribed angle is half the measure of inscribed arc.
![a=\frac{1}{2}\cdot 99](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B1%7D%7B2%7D%5Ccdot%2099)
![a=49.5](https://tex.z-dn.net/?f=a%3D49.5)
Therefore, the value of a is 49.5 units.
We know that measure of all angles of a triangle is 180 degrees. The measure of 3rd angle will be half the measure of c, so we can set an equation as:
![a+b+\frac{1}{2}c=180](https://tex.z-dn.net/?f=a%2Bb%2B%5Cfrac%7B1%7D%7B2%7Dc%3D180)
![49.5+90+\frac{1}{2}c=180](https://tex.z-dn.net/?f=49.5%2B90%2B%5Cfrac%7B1%7D%7B2%7Dc%3D180)
![139.5+\frac{1}{2}c=180](https://tex.z-dn.net/?f=139.5%2B%5Cfrac%7B1%7D%7B2%7Dc%3D180)
![139.5-139.5+\frac{1}{2}c=180-139.5](https://tex.z-dn.net/?f=139.5-139.5%2B%5Cfrac%7B1%7D%7B2%7Dc%3D180-139.5)
![\frac{1}{2}c=40.5](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dc%3D40.5)
![\frac{1}{2}c\cdot 2=40.5\cdot 2](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dc%5Ccdot%202%3D40.5%5Ccdot%202)
![c=81](https://tex.z-dn.net/?f=c%3D81)
Therefore, the value of c is 81.
