Answer:
Option B. 9.11
Step-by-step explanation:
To find the length of line AB, we must first of all calculate the value of θ as shown in the attached photo.
The value of θ can be obtained as follow:
θ + 39° + 120° = 180° (sum of angles in a triangle)
θ + 159° = 180°
Collect like terms
θ = 180° – 159°
θ = 21°
Thus, we can obtain the length of line AB by using sine rule as illustrated below:
b/Sine B = c/Sine C
b = 16
Angle B = 39°
Sine C = 21°
c =?
b/Sine B = c/Sine C
16/Sine 39° = c/Sine 21°
Cross multiply
c × Sine 39° = 16 × Sine 21°
Divide both side by Sine 39°
c = (16 × Sine 21°) / Sine 39°
c = 9.11
Therefore, the length of line AB is 9.11
11>12c because 26-15>12c which equals 11>12c
Answer:
The answer is B.
Step-by-step explanation:
A=3.14 x 12.5>2
A= 3.14 x 156.25 =490-.625
A= 490.625 x 16m
A= 7, 850 m3
The correct answer is that she picked 16 green peppers. We can work this
out because 16 + 4 = 20, and 4 x 4 is 16, so therefore there were 16
green peppers and 4 red peppers.
Answer:
The width of the window should be 
and the height of the window should be 
Step-by-step explanation:
we know that
The circumference of a semicircle (window) is equal to
we have that
substitute and solve for r
so
the width of the window is equal to the diameter of the semicircle
so
The width of the window should be 
and the height of the window should be
