Answer:
r= 
Step-by-step explanation:
The sum to infinity of a geometric series is calculated as
S∞ =
; | r | < 1
where a₁ is the first term and r the common ratio
here a₁ = 15 and S∞ = 45 , then
45 =
( multiply both sides by (1 - r ) )
45(1 - r) = 15 ( divide both sides by 45 )
1 - r =
=
( subtract 1 from both sides )
- r =
- 1 = -
( multiply both sides by - 1 )
r = 
Straight lines will always add up to 180 degrees, so the angle that is missing here is supplementary to the other angle(adds up with the other angle to get 180) so we take 79 away from 180 and get 101 degrees
Answer:

Step-by-step explanation:
<u>Trigonometric ratios</u>

where:
is the angle- O is the side opposite the angle
- A is the side adjacent the angle
- H is the hypotenuse (the side opposite the right angle)
Given:
= G- A = GF = 2
- H = EG = 4
