Answer:
x = 26
Step-by-step explanation:
The parallel lines are Line l and Line m. The other line shown is the transversal.
When 2 parallel lines are cut by a trasversal it creates 4 euqual angles and another 4 equal angles of different measure.
The angle "5x + 7" is equal to the angle "8x - 71" since they are <em><u>alternate exterior angles.</u></em>
<em><u /></em>
So, we can equate both expressions and use algebra to solve for "x". The process is shown below:
Hence,
the value of x is 26
You could do 90 x 70 and get 6300
If you are good at mental math you might try 90 x 68 or 92 x 70 to get even closer to the real answer.
Answer:
inches
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
= 2πr ×
= 2π × 10 ×
= 20π × = = inches
The <em>correct answers</em> are:
A) circumcenter
B) incenter
C) centroid
D) orthocenter.
Explanation:
These are all definitions of these terms.
The circumcenter is defined as the point of intersection of the perpendicular bisectors.
The incenter is defined as the point of intersection of the angle bisectors.
The centroid is defined as the point of intersection of the medians.
The orthocenter is defined as the point of intersection of the lines containing the altitudes.
I'm pretty sure line XZ is the only line there.
