Since a triangles angles add up to 180 you would add the other sides and then
180-161=19
So angle 1 is 19 degrees
Answer:

Step-by-step explanation:
Given:
Consecutive Terms: k-5, k+7, k+55
Required:
Determine the value of k
To do this, we make use of the concept of common ratio.
The common ratio (r) of a geometric sequence is:

In other words:

Where 1, 2 and 3 represents the terms of the progression/sequence
So:
becomes

Solve for k


Multiply both sides by 30, to get rid of fractions... 12 + 30m = 25, subtract both sides by 12... 30m = 13. Divide both sides by 30, m = 13/30
