Answer:
9 cm
Step-by-step explanation:
Given that angle Y = 90 means that the triangle is a right angle triangle
If angle X = 30 degrees and xz =18 cm
xz is the hypotenuse side while zy is the opposite side considering the angle at X
Hence using the notation SOH CAH TOA
SOH
Sin X = zy/xz
Substituting
Sin 30 = zy/18
cross multiply
zy = 18 sin 30
zy = 18 * 0.5
= 9 cm
Answer:
556
Step-by-step explanation:
Surface area of the cuboid=2*(lb+bh+lh)
Surface area=2*(110+80+88)=556
Procedure:
If you have a fraction turn it into a decimal by doing this:
6/10= 0.6
this works because the 6 is in the tenths place and it is 6/10 as a fraction.
It works with thousandths and hundreths:
4/100=0.04
9/1000=0.009
This works with even bigger place values.
Each variable used is the first letter of each of their names.
t+b+c=87
c=2t
b=t+7
Substitute for b and c
t+ (t+7)+2t= 87
4t+7=87
4t=80
t=20
Plug in the known t value.
c=2(20)
c=40
b=20+7
b=27
Final answer: Tammy=$20, Boris= $27, Carlos=$40
