Answer:
2x+4
Step-by-step explanation:
Well, if you are asking how to do it, than you would probably first make a book, then on each page write a different math statagy, such as using the factor tree.
Answer:
Angle 3x = 75 x=25
Angle y=105
Step-by-step explanation:
The angle that measures 75° and the angle that measures 3x are both verticals angles. By using the Verticle angle theorem we can conclude that they are congruent. Therefore, 3x=75.
To find y, you can conclude that the angle that measures 75 is supplementary to angle y. Therefore, you minus 75 from 180 to get your value of y, 105.
Answer:

Step-by-step explanation:
The sine of an angle is equal to the y coordinate point where the terminal side of the angle intersects the unit circle.
