X = 15°
Given that the angle with m < 165° and m< x° are supplementary angles whose sum add up to 180°,
We can add their sum by establishing the following formula:
m < 165° + x° = 180°
Subtract m< 165° from both sides
m < 165° — m < 165° + x° = 180° — m < 165°
x° = 180° — m < 165°
x° = 15°
Therefore, the value of x = 15 °
Answer: k = 200/3
Step-by-step explanation:
If a variable, a varies directly with a variable, c, it means that as a increases, c increases and as a decreases, c decreases.
Also, If a variable, a varies inversely with a variable, b, it means that as a increases, b decreases and as a decreases, c increases.
The variable c varies directly with a and inversely with b. We would introduce a constant of variation, k. Therefore
a = kc/b
If c = 3/20 when a = 2 and b =5, then
2 = (k × 3/20)/5 = 3k/100
Cross multiplying, it becomes
3k = 100 × 2 = 200
k = 200/3
Lets just say hypothetically that x=7. So to find the odd number before 7 we need to subtract a number. The odd before 7 is 5 which is 7-2. So by subtracting 2 from a odd value you get the odd value befire it so your equation is x-2
-4.5=-0.5(x-7.1)
9=x-7.1
16.1=x
