In the rhombus m 1=18x m 2=x+y and m 3=30z. Find the value of x+y+z
ra1l [238]
A Rhombus has four equal straight sides. We can assume that the rhombus in this problem is square-shaped with 90° angles.

m1 = 18x ; 90 = 18x ; 90/18 = x ; 5 = x
m2 = x + y ; 90 = 5 + y ; 90 - 5 = y ; 85 = y
m3 = 30z ; 90 = 30z ; 90/30 = z ; 3 = z

x = 5 ; y = 85 ; z = 3

x + y + z ⇒ 5 + 85 + 3 = 93

The circumference of a circle is approximately 39.25 mm. What is the length of the diameter?
melomori [17]

Answer:

<h2>12.5 millimeters (mm).</h2>

Step-by-step explanation:

<u>Explain/define:</u>

<u>CIRCUMFERENCE: THE DISTANCE AROUND A CIRCLE.</u>

<u>DIAMETER: THE LENGTH OF A STRAIGHT LINE THROUGH THE CENTER OF A CIRCLE.</u>

<u>Mathematics: Formula</u>

d=c/3.14

d-diameter

c-circumference

<u>Mathematics: Solve</u>

To find the length of the diameter from the circumference, divide the circumference by pi. The quotient is the diameter.

3.14 is often used for pi.

39.25/3.14=12.5.

<u>Conclude:</u>

Therefore, the length of the diameter of the circle is 12.5 millimeters (mm).
