Answer:
B) -3
Step-by-step explanation:
The sum of the three angles of any triangle is equal to 180 degrees.
180-50-87 = 43.
43 = x+46
x = 43-46
x = -3
You have to add all of your frequency’s together and divide by 6 for the 6 scores. your mean would be 2
Answer:
Step-by-step explanation:
For a rhombus, the opposite angles are equal:
74=5y+9
5y=65
y=13
For a rhombus, the adjacent angles are supplementary:
74+(z-10)=180
z-10=106
z=116
74+(x+7)=180
x+7=106
x=99
