Answer:
x = 6.6
Step-by-step explanation:
Data obtained from the question include the following:
Angle X = 15°
Angle Y° = 23°
Side y = 10
Side x =..?
The value of side x can be obtained by using the sine rule as shown below:
x/Sine X = y/Sine Y
x/Sine 15 = 10/Sine 23
Cross multiply
x × Sine 23 = 10 × Sine 15
Divide both side by Sine 23
x = (10 × Sine 15) / Sine 23
x = 6.6
Therefore, the value of x is 6.6.
Answer:
![- \frac{8}{7}](https://tex.z-dn.net/?f=%20-%20%20%5Cfrac%7B8%7D%7B7%7D%20)
Step-by-step explanation:
y2-y1 / x2-x1
x1 = 1
x2 =-6
y1= 1
y2= 9
![\frac{9 - 1}{ - 6 - 1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B9%20-%201%7D%7B%20-%206%20-%201%7D%20)
=
![\frac{8}{ - 7}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7B%20-%207%7D%20)
=
![- \frac{8}{7}](https://tex.z-dn.net/?f=%20-%20%20%5Cfrac%7B8%7D%7B7%7D%20)
