Answer: GCE
Step-by-step explanation:
This is because supplementary angles add up to 180 degrees. By assuming GCE is 70 degrees, and GCE is 110 degrees, we get 180 degrees. Plus, both of those angles share the same vertex.
The value of the 5 in 58 is 50
the value of the 8 in 58 is 8
50 + 8 = 58
a.
This is the geometric sequence: a1 = 1.5 m = 150
cm, r = 0.74
The formula now is an = a1 x r ^ n-1
Just substitute a1 = 150 cm and r = 0.74
an = 150 x (0.74) ^ n – 1
b.
The second part is:
A6 = 150 x 0.74 ^ 6-1
= 150 x 0.74 ^5
= 150 x 0.221906624
= 33.28509936 cm
Answer:
Step-by-step explanation:

From the initial condition,

So we have that 
Answers: choice C and choice E
Plugging x = 3 and y = -1 into both equations of choice C lead to a true result (the same number on both sides). This is why the system of equations listed in choice C is one possible answer. Choice E is a similar story.
If your teacher didn't mean to make this a "select all that apply" type of problem, then it's likely your teacher may have made a typo.
