<span>Angles on one side of a straight line always add to 180°.
Look at the picture.
a = 180° - 134° = 46°
b = 180° - 130° = 50°
</span><span>In a triangle, the three interior angles always add to 180°.
a + b + c = 180°
c = 180° - (46° + 50°) = 180° - 96° = 84°
x° = 180° - 84° = 96°
</span>
<span>We can see that:
x = a + b

Answer:
The equation is x =
Step-by-step explanation:
The Equation is formed from two sides equal to each other
- In the algebraic statement "is" means equal
- In the algebraic statement "of" means times (×)
∵ One eighth means
∴ Negative one eighth means
→ Assume that the number is x
∵ "of" means times
∴ Negative one eighth of a number = × (x)
∴ Negative one eighth of a number = x
∵ Negative one eighth of a number is
→ "is" means equal, so the left side is x and the right side is
∴ x =
⇒ Equation
∴ The equation is x =
