Answer:
79° is the measure of the required angle
since it is the vertically opposite angle of AOB.
Answer:
complementary angles
Step-by-step explanation:
That square drawn by the vertex of those angles indicates that the angle formed by the vertical ray pointing up and the horizontal ray pointing right is a right angle. A right angle measures 90 degrees. The measures of the angles measuring x and 71 add up to 90 degrees.
Definition:
Complementary angles are two angles whose measures have a sum of 90 degrees.
The angles measuring x and 71 are complementary angles.

Answer:
Mark has 18 shirts
Given that together they have 140 shirts.
x + 7x - 4 = 140
8x = 140 + 4
8x = 144
x = 144/8
x = 18
Joe has 122 shirts
7x - 4
7 × 18 - 4
126 - 4
= 122
The trigonometric functions have features that are worthy of note. Among these features are the period and the amplitude. The graph of f(x)=cos x repeats itself along the x-axis by a certain distance. This distance is called the period. For the cosine function, the period is 2pi radians. It can also be observed that the graph goes up and down by a certain distance. This distance is called the amplitude. For the curve of f(x)=cos x, the amplitude is 1. The main difference between a cosine function and a sine function is that the former is symmetric with respect to the y-axis while the latter is symmetric with respect to the origin.
