That's a trapezoid,
Answer: 32
But say we didn't know the formula. We can chop out the 4 by 4 square and we have two 45/45/90 triangles side 4 left over, so two 4 by 4 squares,
A = 2(4)(4) = 32
We can think of this as 12 by 4 rectangle with two 4 by 4 right triangles chopped out:
A = 12(4) - 2(1/2)(4)(4) = 48 - 16 = 32
Answer:
A
Step-by-step explanation:
Remark
f and d are equal (and acute) because they are corresponding angles.
82 and f are supplementary, so we can find f
Finding f
f + 82 = 180
f = 180 - 82
f = 82
Finding d
d = f
d = 82

Answer:
Step-by-step explanation:
The total number of operations prepared by the surgeon is X.
The questions can be solved by set
For two sets A and B,
Where A= The surgery done with infections
B= Surgery done which failed
n(AᴜB) is the number of elements present in either of the sets A or B.
n(A∩B) is the number of elements present in both the sets A and B.
Y= number of surgery which succeed and are free from infection
n(AᴜB) = n(A) + (n(B) – n(A∩B) + Y
X= 2% of X + 12% of X -1.35% of x + Y
X=0.02X+0.12X-0.0135X+Y
X=0.1265X+Y
Y=X-0.1265X
Y=0.8735X
Therefore the operation s that succeed and are free from infections is 0.8735 or 87.35%
