Answer: 4m
Step-by-step explanation:
Note : midpoints divide a line into two equal parts.
To calculate the length of SA;
We can consider the large triangle QRS with
Two midpoints :
A on the line QS, QA = 4m ;
and B on the line RS with RB = 3m
Fron the definition of midpoint :
QS = QA + AS
where QA = AS
QS = 2QA = 2AS
Therefore,
QA = QS
4m = 4m

Answer:
45,45,90
Step-by-step explanation:
3x + 3x + 6x= 180
12x=180
x= 180/12= 15
3x=3×15=45
3x=3×15=45
6x=6×15=90
Answer:
2(s-c)/ a^2 = v
Step-by-step explanation:
s = 1/2 a^2 v+c
Subtract c from each side
s -c = 1/2 a^2 v+c-c
s-c = 1/2 a^2 v
Multiply each side by 2
2(s-c) = 2* 1/2 a^2 v
2(s-c) = a^2 v
Divide each side by a^2
2(s-c)/ a^2 = a^2 v /a^2
2(s-c)/ a^2 = v
