Answer:s
12 weeks
Step-by-step explanation:
if keith starts with $500 and wants to end with (at least) $200
he can withdrawn up to $500-$200=$300
if he withdraws $25 week the $300 will last $300 $25 week =12 weeks
C^2=a^2+b^2-2abcosC
13^2=10^2+11^2-2×10×11×cos(°)
169=100+121-220cos(°)
220cos(°)=100+121-169
220cos(°)=52
cos(°)= 13/55
°=cos-1(13/55)
°=76.328°
Answer:
triangles AQB and AVB are congruent.
ΔLKJ ≅ ΔLMJ
Step-by-step explanation:
We have to prove that triangles LKJ and LMJ are congruent so let's
Consider triangles LKJ and LMJ;
∠KLJ=∠MLJ {Given that LJ bisects ∠KLM}
∠KJL=∠MJL {Given that LJ bisects ∠MJK}
LJ=LJ {common side}
So using ASA, triangles AQB and AVB are congruent.
Hence it is proved that
ΔLKJ ≅ ΔLMJ
For 2n it would be 15 upwards , so any number over 15.
5n would be any number about 20
