PLEASE HELP! Given: △MNO m∠M=45°, m∠O=30° MN=6 Find: NO, MO.
zubka84 [21]

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

If A = 117 degrees, B = 12 degrees, and b = 12, find a. Round to the nearest tenth.​
ludmilkaskok [199]

Answer:

<h2>a = 51.4</h2><h3></h3>

Step-by-step explanation:

<u>sinA</u> = <u>sinB</u>

  a         b

<u>sin(117)</u> = <u>sin(12)</u>

   a             12

a * sin(12) = 12 * sin(117)

a = <u>12 * sin(117)</u>

         sin(12)

a = 51.4

Petra claims that he can use the Associative Property of Multiplication to rewrite (9.5 x 9) + 1 as 9.5 X 10. Is Petra correct?
My name is Ann [436]
No, he is wrong.

(9.5 x 9) + 1 = 86.5
9.5 x 10 = 95
