Answer:
A(1)=4
A(n)= A(n-1)-5
Step-by-step explanation:
Plug in 1 to see that a(1)=4. Then, find a few more using the given formula and see what the change is from one to the next. It ends up subtracting 5 for every value.
Answer: b+14

Answer:
142° is the measure of angle 2.
Step-by-step explanation:
When two lines intersect, they make four angles. The angles facing each other are equal.
Let's say that two lines a and b intersected each other to make angles 1,2,3 and 4 respectively.
The measure of angle 3 = 38 degrees.
We know that the angle 1 is against angle 3 and is equal to 38.
Also Angle 2 and Angle 4 are also against each other and are equal let's say equal to x degrees.
Now, the sum of all four angles = 360 degrees
∠1 + ∠2+ ∠3 + ∠4 = 360°
38° + x + 38° + x = 360°
2x = 360° - 76°
2x = 284°
x = 142°
Hence, ∠2 = 142°
Bah ahaha because i’m trying to get answers to m
