Answer:
see explanation
Step-by-step explanation:
(a)
The angles are vertical and congruent, that is
x - 10 = 125 ( add 10 to both sides )
x = 135
-------------------------------------------------
(b)
Supplementary angles sum to 180°
The angles are in the ratio 2 : 3 = 2x : 3x ( x is a multiplier ), then
2x + 3x = 180
5x = 180 ( divide both sides by 5 )
x = 36
thus
2x = 2 × 36 = 72
3x = 3 × 36 = 108
Then the 2 angles are 72° and 108°
Answer:
420
Step-by-step explanation:
15%= 0.15
2800*0.15= 420
Answer:
I think the last one doesn't fit in
13, 15, 23, 24, 25
Median is 23 because it comes in middle of five numbers
To find the mean, add up the values in the data set and then divide by the number of values that you added
if we sum these numbers we get 100 then divide it by 5 we get
100/5 = 20
