19/100 and 0.19 are the answers.
d=rt
300=r4.5
divide both sides by 4.5
66 and 2/3=r
the rate is 66 and 2/3mph
p=2(l+w)
90=2(20+w)
divide both sides by 2
45=20+w
minus 20 both sides
15=w
width=15in
Answer:
B. If ΔKLM ≅ ΔPQR and ΔPQR ≅ ΔSTU, then ΔKLM ≅ ΔSTU
Step-by-step explanation:
The transitive property in general says ...
if a=b and b=c, then a=c
The transitive property of congruence replaces the equal sign with a congruence symbol, and replaces a, b, c with any geometric figure. Here, the geometric figures used are triangles KLM, PQR, and STU.
If ΔKLM ≅ ΔPQR and ΔPQR ≅ ΔSTU, then ΔKLM ≅ ΔSTU
Answer:
m<ACB=1/2 of m<AOB
so m<ACB=45⁰÷2
m<ACB=22.5⁰
I HOPE IT HELPS HAVE NICE DAY!
