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: x= -(1/2)
Step-by-step explanation:
(x+5 +3) / x+3 = 3
Multiply both sides by (x+3)
(x+8)= 3(x+3)
x+8 = 3x+9
-2x = 1
x= -1/2
CHECK:
-1/2 +8 = 15/2 -1/2+3 =5/2
15/2 : 5/2 = 15/2*(2/5) = 30/10 = 3
