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.

75 is 25% more than 60, but 60 is 20% less than 75, explain why?
xxMikexx [17]

Answer:

Explanation:

15 goes into 60, 4 times (1 fourth is equal to 25%).

15 goes into 75, 5 times (1 fifth is equal to 20%)

So 75 is one fifth more because it has a value of 15 more, and 60 is 1 fourth less than 75 because its value is more minuscule and less is more.

If you don't understand this was quite the challenge to explain.

Triangle A B C is shown. Angle A C B is a right angle. An altitude is drawn from point C to a point on side A B to form a right
mars1129 [50]

Answer:

BC=15\ units

Step-by-step explanation:

see the attached figure to better understand the problem

In the right triangle ABC

Applying the Pythagorean Theorem

AB^2=AC^2+BC^2

substitute the given values

17^2=8^2+BC^2

solve for BC

BC^2=17^2-8^2

BC^2=225

BC=15\ units

-(5a+6)=2(3a+8) what is the answer
ValentinkaMS [17]

Answer:

a = -2

Step-by-step explanation:

-(5a+6)=2(3a+8)

-5a -6 = 2*3a +2*8

-5a -6 = 6a +16

-5a -6a = 16+6

-11a = 22

a= -22/11

a = -2
