#a
m<5=40°
#b
m<2=140
#c
<5 and <2 are linear pair(looked properly in diagram) Hence they are supplementary.
#d
<5 and 2 are same side interior angles (Clearly shown on diagram .
- We can call them co responding interior angles and their sum will be 180 if lines are parallel
#e
a||b
Let's verify
Let the angle below <1 be <3
Now
<2+<3=180
<5+<4=180
Hence verified
Answer:
x = 3.431
Step-by-step explanation:
Given equation is,
By taking log on both the sides of the equation,
(3x - 9)log5 = log8
3x - 9 =
3x - 9 = 1.292
3x = 9 + 1.292
x =
x = 3.4306
x ≈ 3.431
The correct answer would be J
The answer is 2.35714285714!
hope this helps!!
Step-by-step explanation:
a square has 4 identical sides.
so, when you have to "walk" around the perimeter of a square you have to go 4 times the same distance.
therefore
20 = 4×side length
side length = 20/4 = 5 in
it is a 5 in × 5 in square.
FYI a rectangle has 2 pairs of sides that are equally long inside their pair.
and so you have in this case a perimeter of
2×6 + 2×4 = 12 + 8 = 20 in
