Answer:
1. Adjacent and formed a linear pair
2. Adjacent and formed a linear pair
3. Adjacent
4. Not adjacent
Step-by-step explanation:
In essence, adjacent angles are two angles side by side. Two adjacent angles can form a linear pair when they are created by two lines intersecting. So, in broad terms, they are adjacent on a flat plane (or a straight line), and together they make a 180° angle.
Option C:
The perimeter of the rhombus is 100 inches.
Solution:
AC = 30 inches, BD = 40 inches
In rhombus, diagonals bisect each other at right angles.
AE = CE = 15 inches
BE = ED = 20 inches
In ΔAED, ∠E = 90°
Using Pythagorean theorem,





Taking square root on both sides, we get
AD = 25 inches
In rhombus, all sides are equal in length.
AD = DC = CB = BA = 25 inches.
Perimeter = AD + DC + CB + BA
= 25 + 25 + 25 + 25
= 100 inches
The perimeter of the rhombus is 100 inches.
Option C is the correct answer.
Answer:
4 2/3
Step-by-step explanation:
2 , 4, 6, 5, 4, 4, 5, 4, 8
Add the data together then divide by the number of data points
(2 + 4+ 6+ 5+ 4+ 4+ 5+ 4+ 8) /9
42/9
