50 degrees because 50+50= 100 +80 = 180 and there is 180 degrees in a triangle
Answer:
3. 8y= -7x -12
4. -3y= 4x -12
5. 7y= -2x +4
Do you want me to do the rest?
did you got it??
The rest are:
6. -3y =6x +12
7. -10y= 5x+20
8. 4y=2x +12
Answer:
![\displaystyle (0, -1); maximum](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%280%2C%20-1%29%3B%20maximum)
Step-by-step explanation:
First off, <em>B</em> is zero, so there is no <em>phase shift</em>, meaning that the vertex stays on the y-axis. Next, <em>A</em> is negative, so the parabola opens down, and whenever you have a parabola opening down, it does so at maximum. Finally, <em>C</em> represents our y-intercept, or in this case, our <em>vertical shift</em>. Our y-intercept is (0, −1), and so as our vertex, hence our answer.

Ratio of 30-60-90 triangles in terms of side lengths is 1-
![\sqrt{3} ](https://tex.z-dn.net/?f=%20%5Csqrt%7B3%7D%20%0A)
-2
So, the side across the 30-degree angle is 6.25.
Thus, the side across the 90-degree angle (hypotenuse) is 12.5.
