You would need to write a solvable equation, and you can do this because you know that angles in a triangle add up 180° so the missing angle must be (180 - 9x). This makes the equation:
5x + 9 + x + (180 - 9x) = 180
6x + 9 + 180 - 9x = 180
-3x + 189 = 180
- 189
-3x = -9
÷ -3
x = 3
So your answer is x = 3, I hope this helps!
Answer:
it means the value of x
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
hypotenuse^2= leg^2 + leg^2
10^2= 6^2 + x^2
100= 36 + x^2
100-36= x^2
64= x^2
√64=√x^2
8= x
Answer:
8 =x
Step-by-step explanation:
- 18 = -3x + 6
Subtract 6 from each side
-18-6 = -3x+6-6
-24 = -3x
Divide each side by -3
-24/-3 = -3x/-3
8 =x
