Answer:
Statement B, C, E are correct
<u>Solution:</u>
We have to find the true statements
We know that,
To find the diameter of a circle, multiply its radius by two
Thus statement E is correct
Also,
To find the diameter of a circle, divide its circumference by π
Thus statement B is correct
circumference of a circle is obtained by multiplying diameter with pi
The circumference of a circle is greater than its diameter
Thus, Statement C is correct
Answer:
225
Step-by-step explanation:
3x5 is 15, 15 to the 2nd power is 225
Answer:
Equation: (5x + 20) + (3x - 30) + (2x + 10) + 8x = 360
x = 20
Angle B = 30°
Step-by-step explanation:
Given:
<A = 5x + 20
<B = 3x - 30
<C = 2x + 10
<D = 8x
Sum of interior angles of a quadrilateral = 360°
Therefore:
<A + <B + <C + <D = 360°
(5x + 20) + (3x - 30) + (2x + 10) + 8x = 360
Solve for x
5x + 20 + 3x - 30 + 2x + 10 + 8x = 360
Collect like terms
5x + 3x + 2x + 8x + 20 - 30 + 10 = 360
18x = 360
Divide both sides by 18
x = 360/18
x = 20
<B = 3x - 30
Plug in the value of x
<B = 3(20) - 30 = 60 - 30
<B = 30°
I don't understand English because I'm from Mexico, sorry and well I have no explanation xd
