Step-by-step explanation:
Answer:
geometric sequence
Step-by-step explanation:
A geometric sequence is a sequence of numbers that is ordered with a specific pattern. Each successive number is the product of the previous number and a constant. The constant is the same for every term in the sequence and is called the common ratio.
All the interior angles of a triangle always add up to 180 degrees.
3x + (2x + 20) + (4x - 20) = 180
3x + 2x + 20 + 4x - 20 = 180
3x + 2x + 4x + 20 - 20 = 180
10x = 180
x = 180/10
Therefore, x = 18
∠СXA = ∠BXA + ∠СXB = 30°20' + 40°35' = 70°55'
The slope intercept form looks like y=mx+b (m-slope, b is the y intercept)
y+3=1/2(x-2)
y=(1/2)x-(2/2)-3
y=(1/2)x-4
