Answer:
12
Step-by-step explanation:
100=40 in this scenario. 100/40 is 250% or 2.5
30/2.5=12.
Use the law of cosines.
a2+b2−2abcosC=c2
Find the measure of angle C. It is the opposite side of c.
c2−a2−b2−2ab=cosC
cosC=13.62−22.52−182−2(22.5)(18)≈0.797
C=cos−10.797=0.649 rad=37.19∘
angle B:
a2+c2−2accosB=b2
cosB=b2−a2−c2−2ac
B=cos−1b2−a2−c2−2ac=cos−1182−22.52−13.62−2(22.5)(13.6)≈0.927 rad=53.13∘
angle A:
b2+c2−2bccosA=a2
A=89.68∘
1/10x200
= 1/10x200/1
= 200/10
=20
the answer is 20
if u dont understand, 1/10 means a part of 200 that is divided by 10 which means the number x10 =200. So if u dont understand, you can check answer this way: n*10=200
200/10=n
n= 20
