Answer: M=32°

Step-by-step explanation:

The identity sin²(x)+cos²(x)=1 can help us figure out the value of M. You can see that the problem's format fits exactly the identity. Since x is the same in the identity, we know that M=32°.

What’s the reciprocal of the number 1 1/2?
Pie

Answer:

2/3

Step-by-step explanation:

To find the reciprocal you first have to turn the mixed number into an improper fraction. (multiply denominator by whole number, then add the numerator, the denominator stays the same)

(1 x 2 )+ 1=3>>numerator | denominator stays the same>>2 | 3/2

Since the reciprocal is the number that you multiply by to get one, you can flip the numerator and denominator to get your reciprocal.

3/2>>2/3 ( the denominator came to the numerator, and the numerator came to the denominator)

2/3 is your reciprocal

To check your work, you can multiply the reciprocal and the regular number, if your answer is 1, then your reciprocal is correct. If your answer is anything else other than one, you may want to rethink your work.

correct reciprocal: 2/5 x 5/2 = 1

incorrect reciprocal: 2/5 x 6/2 = 5/6

You cannot assume the angles add to 90, but you know since BD is an angle bisector that ABD is equal to DBC, or x-5=2x-6

x=1. this is the correct solution to the equation but gives negative angles when plugged in which isn't possible. there must be something wrong work the question

5. Xian plans to run 14 laps around a track Each lap is 400 yards. So farxian has run 1,680 yards around the track. What percent
Igoryamba
1,680 divided by 400 = 4.2 
So we know that Xian has done 4.2 laps. 
4.2 divided by 14 = 0.3
0.3 x 100 = 30%
Therefore, Xian has finished 30% of the run
