Answer:
<h3>ya-z/1+y</h3>
Step-by-step explanation:
Making x the subject of the formula;
y=x+z/a-x
Cross multiply
y(a-x) = x+z
ya - yx = x+z
Collect like terms
x+yx = ya - z
x(1+y) = ya - z
x = ya-z/1+y
Hence the value of x is ya-z/1+y
The radius of this circle is (B) 4.9 cm.
<h3>
To find the radius of the circle:</h3>
To solve this problem, we need to, first of all, convert the angle from radians to degrees.
data;
- length of an arc = 18cm
- angle = 7/6π rads
- π= 3.14

Length of an Arc:
The formula for the length of an arc is given:
θ/360 × 
Let's substitute the values and solve:

From the calculations above, the radius of this circle is 4.9cm.
Therefore, the radius of this circle is (B) 4.9 cm.

Complete question
A circle has a central angle measuring 7pi/6 radians that intersects an arc of length 18 cm. What is the length of the radius of the circle? Round your answer to the nearest tenth. Use 3.14 for pi.
(A) 3.7 cm
(B) 4.9 cm
(C) 14.3 cm
(D) 15.4 cm
Step-by-step explanation:
Answer:
4.5 feet
Step-by-step explanation:
One foot is 12 inches, therefore she is 4 (12x4=48) and she would have 6 left over which is half of a foot. (:
So I think it would be 55 because the base times the height = 15 and base length = 40
