Since its a square we put one of the side lengths to the power of 2 3 to the power of 2 equals 9 so the area is 9
If point

is on the unit ircle, then:

Since, the point is in the second quadrant, x is negative.
Thus,

Part A:

Therefore,

.
Part B:

Therefore,
Answer:
f = 26
d=112
e=42
Step-by-step explanation:
as far as what i can see, the first given angle is 112 and the second angle is 42.
These two angles are the angles on one straightline, therefore the missing angle will be 180 - 112 - 42 = 26 (Supplementary angle). This angle is not required and it is the missing angle on the left hand side. However, this angle should be equal to that of f (Opposite angle).
By the same way, d and e are the two opposite angles for 112 and 42, respectively.
Answer:
40
60
Step-by-step explanation:
20÷2=10
10×4=40
10×6=60
The complete question in the attached figure
Part a)
we know that
ABC is a right triangle
∠ACB=45°
AC=hypotenuse------> 6√2 cm
sin 45=AB/AC-----> AB=AC*sin 45----> AB=6√2*√2/2----> AB=6 cm
the answer part a) isAB=6 cmPart b)
we know that
volume of the pyramid=(1/3)*Area of the base*height
area of the base=50 cm²
height=6 cm
so
volume of the pyramid=(1/3)*50*6----> 100 cm³
the answer part b) is 100 cm³
