B -6 because absolute value ignores negatives
Answer:
x = 5
Step-by-step explanation:
The sides are in proportion.
The proportion is 20/36
The other sides must be in the same proportion: 5x / 45
5x/45 = 20/36 You can reduce the left side by dividing top and bottom by 5
1x / 9 = 20/36 You can reduce the right side by dividing by 4
x / 9 = 5/9 at this point you should be able to see that x = 5, because the denominators are the same.
That is the answer.
However you can extend this by cross multiplying
9x = 45 Divide by 9
x = 45/9
x = 5
Answer:
15 cm.
Step-by-step explanation:
It is given that,
Central angle 
Arc length = 33 cm
Formula for arc length :
where, s is arc length, r is radius and 
is central angle in radian.
Substitute s=33 and 
in the above formula.
Multiply both sides by 10.
Divide both sides by 
.
Put 
Therefore, the radius of the circle is 15 cm.
445 i think … i did 49 x 5 = 245 and then 40 x 5 = 200 and added 200+245 = 445
