The measure on angle 0 is 7pie/4. Measure of its reference angle is __ °, and the tan 0 is ___
soldier1979 [14.2K]

Answer:

Reference angle is \frac{\pi }{4} and tan\frac{7\pi }{4} = -1

Step-by-step explanation:

\frac{7\pi }{4} lies in the 4th quadrant

and reference angle for angle in 4th quadrant is 2π - x , where x is the angle given.


and reference angle for \frac{7\pi }{4} is  

2π-\frac{7\pi }{4} = \frac{\pi }{4}

and tan\frac{7\pi }{4} = -tan \frac{\pi }{4}=  -1

Since tan is negative in 4th quadrant ,therefore value will be  negative for the given angle.

(8n+1)(6n-3) please solve in quadratic formula
cestrela7 [59]
Use the distributive property.

(8n+1)(6n-3)=(8n)(6n)+(8n)(-3)+(1)(6n)+(1)(-3)\\\\=48n^2-24n+6n-3=48n^2-18n-3

Linear Functions <br> 7g+3g-10+3=43<br> Step by step solution? <br> Thankss!❤️
Ivahew [28]
7g + 3g - 10 + 3 = 43

(first combine likes terms)

10g - 7 = 43

(then add 7 to both sides)

10g - 7 = 43
        +7    +7

10g = 50

(then divide by 10 to get what g is equal to)

10g = 50
/10     /10

g = 5
