Answer:
1: 36° 2: 122° 3: 122° 4: 38°
Step-by-step explanation:
First start out by getting 2 and 3. so 58+angle 3 has to sum to 180° since they are supplementary and are a straight line. So 180-58=122. Angle 2 is the same since theyre vertical. then since a triangle has 180° total, you subtract from 180 to find the final angle measurement.
We start with 80 and we add 1 on the first day, 2 on the 2nd, 4 on the 3rd, etc..
Looking at the numbers being added
1 = 20
2 = 21
4 = 22
8 = 23
16 = 24

We start with 80 and we add 2n to it where n represents the number of days into the iteration
with n starting at 0
The function that shows how many stamps we have on any given day is
D
S = 80 + ∑ 2n Where D is the number of days we are into the iteration
n=0
NOTE: This starts at day 0 which would be S = 80 + 20 = 80 + 1 = 81 stamps
Example: To find how many stamps we have on D = 4 we would have
S = 80+20+21+22+23+24
= 80+1+2+4+ 8+16
= 111 stamps
Answer:
x+y=68
x-y=15
Step-by-step explanation:
A "sum" means that we will be using addition, while a "difference" indicates subtraction. Anytime we have two unknown numbers we generally use "x" and "y".
