Its basically just subtracting from one another
for example, 6-6 is 6
or -4-3= 7
315. You just need to take the total and subtract by 60.
Answer:
23

Answer:
4. 73
5. 40°
Step-by-step explanation:
The sum of the angles in a triangle is 180°. The sum of angles in a linear pair is 180°.
4. 45° +62° + k° = 180°
... 107 +k = 180 . . . . . collect terms, divide by °
... k = 180 -107 = 73 . . . . . subtract 107
_____
5. ∠STR = ∠SRT = 20°
... ∠STR +∠STU = 180°
... 20° + 4x = 180°
... 4x = 160° . . . . . . . . subtract 20°
... x = 40° . . . . . . . . . . divide by the coefficient of x
Because this equation is an absolute value, it can turn into two different equations:
3x - 2 = 7
3x - 2 = -7
3x = 9
3x = -5
x = 3
x = -5/3
The solution set is {3, -5/3}, Option C.
