Answer:
y=131°
x=53°
Step-by-step explanation:
∠ ABD and ∠ BDC are supplementary.
The sum of the supplementary angles =180 °
thus y-4+x=180...........i
x and 37° are complementary, that is, they add up to 90°
Thus, x=90-37=53°
Using this value in equation 1 we obtain:
y-4°+53° =180°
y= 180°-53°+4°
y=131°
We can see that both triangles are identical to each other, except that the second is bigger than the first. We can also see that the second triangle's side lengths are one unit more than the first. Let's take the top line as an example: Figure 1 is 3 units long while Figure 2 is 4 units long. To find the scale factor, you divide the shorter length by the longer length and in this problem, you would get 3/4, or 0.75% (which is A).

Answer:
2
Step-by-step explanation:
2x^2 -x -3
Because it is raised to 2, it is a quadratic and henceforth has two intersects
3.
A = pi x r^2
48 = 3.141... x r^2
÷ by value of pi
15.278... = r^2
Square root the ans, to get r
Thus, R = 3.908..... So, radius is 3.9
2.
Circumference = pi x diameter
87. = 3.141... x d
÷ by value of pi
27.692............. = diameter
Radius is twice the diameter. So, divide diameter by 2 to find the radius.
27.692.....÷ 2 = 13.846...
Thus, radius is 13.8cm

Using translation concepts, the graph of g(x) is given at the end of the question.
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The parent function is given by:
.
With the changes, we have that:
- f(-x) is the function reflected over the y-axis.
- f(-x) - 2 is the function reflected over the y-axis and shifted 2 units down.
Hence the function will be given by:
.
The graph is given at the end of the answer.
