Answer:
- A. (x + 16) + (6x − 4) = 180
Step-by-step explanation:
Inscribed quadrilateral has opposite angles supplementary.
<u>So</u>
or
<u>Since</u>
- m∠A = x + 16,
- m∠B = x,
- m∠C = 6x - 4,
- m∠D = 2x + 16
we can use either pair of angle measures to work out the value of x and then find the value of each angle.
<u>We can verify the first option is the only correct one.</u>
- m∠A + m∠C = 180°
- (x + 16) + (6x − 4) = 180
Dilation and reflection
-multiplication of - =reflection
example -(x)
-multiplication of any number other than 1=dilation
example 3x
-addition/subtraction inside the function=horizontal translation
Example (x-3)
-addition/subtraction outside the function=vertical translation
Example x-3
The ratio of the areas is the ratio of the squares of the sides ( which is 10:15 or 2:3) so the answer is
2^2 : 3^2 = 4:9.
The ratio of the perimeters = ratio of corresponding side = 2:3.
