Well, lets start with #3!
<1 is equivalent to <3 because they are vertical angles.
This means that <2 and <4 are congruent because they are vertical angles. We know that a straight line is 180 degrees. So, <1 and <2 added together will equal 180, therefore, <2 is ___________
Since the two lines are parallel, any angle on the other side is congruent, as long as that angle is in the same place as the other. So, we can see that <1 and <7 are in the same place, just moved down. So, <7 is __________.
Answer:
n = 6
a = 6 mm
r = 5.19615 mm
R = 6 mm
A = 93.53 mm2 times $3 = $280.59
P = 36 mm
x = 120 °
y = 60 °
r = inradius (apothem)
R = circumradius
a = side length
n = number of sides
x = interior angle
y = exterior angle
A = area
P = perimeter
π = pi = 3.14159...
√ = square root
Answer: Tan O= 5/12
Step-by-step explanation:
Cot O=12/5
Looking at the pythagoras theory
Cot= 1/tan
So
Cot O=1/tango
Cross multiply
CotO tan O=1
Make tan the subject of formula
TanO= 1/Cot O
Cot O=12/5
Substitute for cot O
Tan O= 1/12/5
Tan O= 5/12
Hello,
This answer may be wrong.. But I'm trying to make sure it's not!!
C. 1,008 :)
Length - 14 meters
Width - 7 meters
The length is twice the width - 7 times 2 = 14
There are four sides, two 14m and two 7m. 14 x 2 + 7 x 2 = 42
