PLEASE HELP! Given: △MNO m∠M=45°, m∠O=30° MN=6 Find: NO, MO.

Mathematics
1 answer:
zubka84 [21]3 years ago

Answer:

NO = 8.48 units, MO = 11.59 Units

Step-by-step explanation:

∠M = 45°

∠O = 30°

∠N = 180-(45+30)

∠N = 105°

MN=6 = o

NO = m

MO = n

From sine rule

\frac{sinM}{m}=\frac{sinN}{n}=\frac{sinO}{o}

\\\Rightarrow \frac{sinO}{o}=\frac{sinM}{m}\\\Rightarrow m=\frac{sinM}{\frac{sinO}{o}}\\\Rightarrow m=\frac{sin45}{\frac{sin30}{6}}\\\Rightarrow m=8.48

\frac{sinO}{o}=\frac{sinN}{n}\\\Rightarrow n=\frac{sinN}{\frac{sinO}{o}}\\\Rightarrow n=\frac{sin105}{\frac{sin30}{6}}\\\Rightarrow n=11.59

∴ NO = 8.48 units, MO = 11.59 Units

A family paid $26.400 as a down payment for a home. If this represents 16% of the price of the home, find the price of the home.
Vlada [557]
The correct answer is:

How to find X if P percent of it is Y. Use the percentage formula Y/P% = X

Convert the problem to an equation using the percentage formula: Y/P% = X
Y is 26,400, P% is 16%, so the equation is 26,400/16% = X
Convert the percentage to a decimal by dividing by 100.
Converting 16% to a decimal: 16/100 = 0.16
Substitute 0.16 for 16% in the equation: 26,400/0.16 = X
Do the math: 26,400/0.16 = X
X = 165,000
So $ 165,000 is the price of the home.

I hope this helps you!!

Can a triangle with the angles of 0, 90 , and 90 be considered a triangle?
asambeis [7]

A "triangle" with the angles 0, 90, and 90 degrees cannot be considered a triangle since the two 90 degree angles make a right angle, and 0 degrees would mean a flat line. Rather it would resemble something like a straight U that is stretched sideways.
