Answer: 8 subsets----------------------------------------------------------------------
----------------------------------------------------------------------
There are n = 3 elements in the given set, so there are 2^n = 2^3 = 2*2*2 = 8 subsets. Those 8 subsets are listed below
{a,b,c}
{a,b}, {a,c}, {b, c}
{a}, {b}, {c}
{ }
The first row is the original set. Any set is a subset of itself.
The second row represents subsets with exactly 2 elements.
The third row represents subsets with exactly 1 element
The fourth row is the empty set which can be written as
Answer:
∠2 and ∠5
Step-by-step explanation:
we know that
<u>Alternate Exterior Angles</u> are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal
In this problem
∠12 and ∠2 are alternate exterior angles
∠12 and ∠5 are alternate exterior angles
therefore
∠2 and ∠5 are each separately alternate exterior angles with ∠12

Answer: 24 5 + 9 = 15 + 9 = 24
Step-by-step explanation:
Answer:
x=27
∠JLK=2x+1=2(27)+1=55
Step-by-step explanation:
∠A+∠K=180
3x+13+∠K=180
∠K=167-3x
∠K+∠L+∠J=180
167-3x+39+2x+1=180
207-x=180
x=27
∠JLK=2x+1=2(27)+1=55
Don't worry, you aren't gonna fail. Take a deep breath and relax. Geometry is tricky but you got this. Have a nice night.
