Answer:
Jessiah has 14 pencils
Miles has 28 pencils
Grace has 8 pencils
Step-by-step explanation:
I'm going to assume that you mean Jessaih instead of Jessia because otherwise it would be impossible to solve
Let the # of Jessaih's pencils equal j, # of Grace's pencils equal g, # of Miles' pencils equal m,
j=g+6
m=2j
So m=2(g+6) or 2g+12
Therefore, g+g+6+2g+12, or 4g+18=50, so g = 8
j=8+6, which is 14
m = 2(14), which is 28
Answer:
and ![\sec \theta = -\dfrac{13}{12}](https://tex.z-dn.net/?f=%5Csec%20%5Ctheta%20%3D%20-%5Cdfrac%7B13%7D%7B12%7D)
Step-by-step explanation:
Assume that the terminal side of thetaθ passes through the point (−12,5).
In ordered pair (-12,5), x-intercept is negative and y-intercept is positive. It means the point lies in 2nd quadrant.
Using Pythagoras theorem:
![hypotenuse^2=perpendicular^2+base^2](https://tex.z-dn.net/?f=hypotenuse%5E2%3Dperpendicular%5E2%2Bbase%5E2)
![hypotenuse^2=(5)^2+(12)^2](https://tex.z-dn.net/?f=hypotenuse%5E2%3D%285%29%5E2%2B%2812%29%5E2)
![hypotenuse^2=25+144](https://tex.z-dn.net/?f=hypotenuse%5E2%3D25%2B144)
![hypotenuse^2=169](https://tex.z-dn.net/?f=hypotenuse%5E2%3D169)
Taking square root on both sides.
![hypotenuse=13](https://tex.z-dn.net/?f=hypotenuse%3D13)
In a right angled triangle
![\sin \theta = \dfrac{opposite}{hypotenuse}](https://tex.z-dn.net/?f=%5Csin%20%5Ctheta%20%3D%20%5Cdfrac%7Bopposite%7D%7Bhypotenuse%7D)
![\sin \theta = \dfrac{5}{13}](https://tex.z-dn.net/?f=%5Csin%20%5Ctheta%20%3D%20%5Cdfrac%7B5%7D%7B13%7D)
![\sec \theta = \dfrac{hypotenuse}{adjacent}](https://tex.z-dn.net/?f=%5Csec%20%5Ctheta%20%3D%20%5Cdfrac%7Bhypotenuse%7D%7Badjacent%7D)
![\sec \theta = \dfrac{13}{12}](https://tex.z-dn.net/?f=%5Csec%20%5Ctheta%20%3D%20%5Cdfrac%7B13%7D%7B12%7D)
In second quadrant only sine and cosecant are positive.
and ![\sec \theta = -\dfrac{13}{12}](https://tex.z-dn.net/?f=%5Csec%20%5Ctheta%20%3D%20-%5Cdfrac%7B13%7D%7B12%7D)
Answer: x= 21.6
Step-by-step explanation:
12^2 + 18^2 =x^2
144 + 324 =x^2
468 = x^2
c= 21.633
To the nearest tenth place is c= 21.6
Answer:
7 and 4
Step-by-step explanation:
l*w=A
2(l)+2(w)=P
7*4=28
2(7)+2(4)=22
A right triangle angle is 90 degrees
given js 51 degrees
90-51 = 39 degrees
a is 39 degrees
