I will get you started.
Let sin x = u
Then 7sin^2x -14sinx+2=-5 become
7u^2 - 14u = - 5
7u^2 - 14u + 5 = 0
Steps:
1. Solve for u.
2. Back- substitute for u.
3. Take the arcsin on both sides to find the angle(s).
You finish.
Answer:
8,55
Step-by-step explanation:
use trigonometric functions
ΔJKL : ΔXYZ
for two similar triangles we have this property:
![\frac{JK}{XY} =\frac{KL}{YZ}](https://tex.z-dn.net/?f=%20%5Cfrac%7BJK%7D%7BXY%7D%20%3D%5Cfrac%7BKL%7D%7BYZ%7D%20%20)
plugging the given values to find x
![\frac{6}{9} =\frac{8}{x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6%7D%7B9%7D%20%3D%5Cfrac%7B8%7D%7Bx%7D%20%20)
cross multiplying ,
6*x=8*9
6x =72
x=12
Answer:
6600 yrds
Step-by-step explanation:
sorry if its wrong
D because your body is the same but lowers because the ground mostly has more moist which gets wet and makes you colder. So yes, it’s d
