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
Let
x--------> number of dogs that completed the obedience class
we know that
total number of dogs=5
<span>Eighty percent of the dogs have completed obedience classes
so
x=0.80*5------> x=4
the answer is
4 dogs </span>have completed obedience classes
D. Neither A nor B. There you go.
15 x 25 = 375
15 x 50 = 750
375 + 750 = 1,125
