Answer: original angle = 75°
Its supplement 105°
Its complement = 15°
Step-by-step explanation:
We know that,
- Sum of supplementary angles is 180 degrees.
- Sum of complementary angles is 90 degrees.
Let x be the original angle , then its supplement = 180° - x
its complement = 90° - x
As per given,
180° - x = 7(90° - x)
⇒ 180° - x = 630° - 7x
⇒ 7x- x = 630° -180°
⇒ 6 x = 450°
⇒ x = 75° [divide both sides by 6]
So, original angle = 75°
Its supplement = 180° - 75° = 105°
Its complement = 90° -75° = 15°
Hence, original angle = 75°
Its supplement 105°
Its complement = 15°
1.2% of 8th grade students is the percentage change.
By taking x as subject the formula becomes x = (v² - u²)/2a.
<h3>What is Equation?</h3>
An equation is a mathematical statement with an 'equal to=' symbol between two expressions that have equal values.
Here given equation:
v² = u² + 2ax
2ax = v² - u²
x = (v² - u²)/2a
Thus, by taking x as subject the formula becomes x = (v² - u²)/2a.

I think you mean like a number decreasing at a percentage. Yea it’s gonna be positive cause like it’s a number but then it’s probably gonna say decreasing making it negative or increasing making it positive. I’m pretty sure, correct if I’m wrong.
Answer:
Just the second one is correct
