Answer:
x = -2
x = 8
Step-by-step explanation:
Excluded values are the ones which make the denominator zero
3x² + x - 10
3x² + 6x - 5x - 10
3x(x + 2) - 5(x + 2)
(x + 2)(3x - 5)
x² - 6x - 16
x² - 8x + 2x - 16
x(x - 8) + 2(x - 8)
(x - 8)(x + 2)
[(x + 2)(3x - 5)] ÷ [(x - 8)(x + 2)]
(3x - 5)/(x - 8)
So excluded values are 8, -2
(8,1);((-2,-6)
2•8-3•1>=12
16-3>=12
13>=12
2•(-2)-3(-6)>=12
-4+18>=12
14>=12

Answer: 
Step-by-step explanation:
1. You have the following information:
- The lenght of 
is 2 centimeters.
- The angle m∠S=80°.
- Cos80°=0.17
2. Therefore, you can calculate the lenght of the segment 
as following:
3. Substitute values and solve for :
4. To the nearest tenth:
Answer:
60, 36, 84
Step-by-step explanation:
The angles of a triangle always add up to 180 degrees.
If the ratios are 5:3:7, that means that there are 15 pieces that we can break up the 180 degrees by.
180/15 = 12
Each value is 'worth' 12 degrees.
Thus the angles would be the ratios multiplied by 12.
5 x 12 = 60
3 x 12 = 36
7 x 12 = 84
