A plane headed due south is traveling with an airspeed of 160 miles per

Mathematics

Answer:

60 °

Step-by-step explanation:

Applying the law of sine we have the following:

160 / Sin B = 80 / Sin 30 °

We solve for B and we have:

160 / Sin B = 80 / 0.5

160 / Sin B = 160

Without B = 160/160

B = Arc Sin (1)

B = 90 °

Now to calculate the other angle (true

 course) would be:

A = 180 ° - (B + C)

A = 180 ° - (90 ° + 30 °)

A = 60 °

That is to say that true course is 60 °

How do i solve this rational expression r-4/5r=1/5r+1
NNADVOKAT [17]

r - 4/5r  =  1/5r + 1

Subtract  1/5r from each side:    r - 4/5r - 1/5r  =  1

Combine all the 'r' terms on the left side: 

                                 r - 5/5r  =  1

                                 r  -  r  =  1

                                       0  =  1

There is no value of 'r' that can make ' 0 = 1 ' a true statement.
So the equation has <em>no solution</em>.

Find the measure of angle x in the figure below: A.) 35° B.) 48° C.) 69° D.) 78°
prisoha [69]

Answer:

x = 48

Step-by-step explanation:

First find y

52+y+59 = 180 since they from a straight line

y = 180-59-52

y = 69

Then we know the angles of a triangle add to 180

x+y+63 = 180

x+69+63 = 180

x = 180-69-63

x =48

How many times does 96 go into 195
Anna007 [38]
You can also do the division with remainders to find the answer:

195 ÷ 96 = 2,041666666666667

So you can clearly see that there are more than two but less than three 96s in 195. So multiply 96 by 2 and then substract the result from 195 to find the remainder:

96 * 2 = 192
195 - 192 = 3

It means that in 195 there will fit two 96s with a remainder of 3.

We can also write it as two 96s and 3/96, what can be further simplified to two 96s and 1/32.
