Answer:
4
Step-by-step explanation:
the y intercept three is 4 away from -1
Based on the calculations, the value of x in this rhombus is equal to: B. 55.
<h3>How to determine the value of x?</h3>
Since the opposite angles in a rhombus are always congruent, the sum of each angle in any rhombus must be equal to 360 degrees.
From the image of the rhombus, we can deduce the following parameters:
Adjacent angles = 2x + 20 and 50 degrees.
Opposite angles = 2x + 20 and 50 degrees.
Adding the angles, we have:
2x + 20 + 2x + 20 + 50 + 50 = 360
4x + 140 = 360
4x = 360 - 140
4x = 220
x = 220/4
x = 55°

<h2>SOLVING</h2>

How do the graphs f(x) and f^-1(x) relate?

These two functions are inverses of each other.
That's the way these two are related to each other.
f^-1(x) is the inverse function of f(x), and f(x) is the inverse function of f^-1(x).




The measure of angle a is 70 degrees
<h3>How to determine the measure of a?</h3>
The angle in a semicircle is a right angle.
This means that:
a + d = 90
Where O is the center of the circle
From the figure, we have:
Angle d and the angle with a measure of 20 degrees are corresponding angles
This means that
d = 20
Substitute d = 20 in a + d = 90
a + 20 = 90
Subtract 20 from both sides of the equation
a = 70
Hence, the measure of angle a is 70 degrees
