Answer:
Perimeter of ΔLMN = 80 units
Step-by-step explanation:
From the figure attached,
m∠K = m∠N = 58°
m∠J = m∠M = 76°
m∠I = m∠L = 46°
Therefore, ΔKJI and ΔNML are the similar triangles.
By the property of similar triangles,
"Corresponding sides of two similar triangles are proportional"
NM =
NM = 22.5
Perimeter of the triangle LMN = ML + NM + NL
= 27.5 + 22.5 + 30
= 80 units
Answer:
The statement is true
The lines are perpendicular
Step-by-step explanation:
we have
----> equation A
The equation A represent a vertical line (is parallel to the y-axis)
The slope is undefined
----> equation B
The equation B represent a horizontal line (is parallel to the x-axis)
The slope is equal to zero
Remember that
The y-axis and the x-axis are perpendicular lines
so
Line A and line B are perpendicular lines too
therefore
The statement is true
