Answer:
It's true.
Explanation:
2(segment ST) = RT
divide both sides by two
ST = RT/2
You would have two equal halves of RT. One half equals RS. The other half equals ST.
Here's a rough picture of the line.
R _____________S_____________ T
S is in the middle of the line which makes it the midpoint.
It's true. S is the midpoint of RT.
5m-n
Just replace m with 4 and n with 9
5(4)-9=20-9=11
Answer:
We use cosine rule also called cosine law which states
c^2=a^2+b^2-2abcosC
given
a=8cm, b=7cm, c=9cm cos C?
9^2=8^+7^2-2*8*7 cos C
expand
81=64+49-112 cos C
like terms together
81-113=-112 cos C
-32=-112cos C
multiply both sides by -1
32=112cos C
divide both sides by 112
32/112=cos C
cosC=0.2857
find cos inverse of 0.2857
angle C= 73.40
