Answer:
(5/2, +-(square root 17)/ 2)
Step-by-step explanation:
1. find a,b, and c of the quadratic
2. use the quadratic formula to solve
The formula for finding the sum of a finite geometric series is
n = 17,
, r = 2
Substitute into the formula and you get 393213
A. 1 = 3/3 = 4/4 = 52/52 = x/x
B. 5 = 10/2 = 15/3 = 7.5/1.5 = 120/24 = 5a/a
All the ratios must equal each other
Answer:
140°
Step-by-step explanation:
<u>Given:</u>
Dana draws a triangle with one angle that has a measure of 40∘.
<u>Question asked:</u>
What is the measure of the angle’s adjacent exterior angle?
Solution:
<u>As we know:</u>
<u><em>Sum of the adjacent interior and exterior angles is 180°.</em></u>
Interior angle = 40°
Adjacent exterior angle = ?
Interior angle + Adjacent exterior angle = 180°
40° + Adjacent exterior angle = 180°
<u>By subtracting both sides by 40°</u>
40° - 40° + Adjacent exterior angle = 180° - 40°
Adjacent exterior angle = 140°
Therefore, the measure of the angle’s adjacent exterior angle will be 140°.
So will be choice D.
bc. 5/6 = 10/12 = 2*5/2*6 = 5/6
