Hey!!
here is your answer >>>
As we have learnt, the sum of angles A and B is exterior angle ,
so,
angle B would be
( 52 + x ) = 110
x = 110 - 52
x = 58!.
angle B is 58°
Sum of all angles in a trinagle is 180!.
angle C would be ,
52 + 58 + c = 180
110 + c = 180
c = 70
angles C is 70° !.
Hope my answer helps!

Answer: C. 541.60 hours
Step-by-step explanation:
Since the lifetime of a 2-volt non-rechargeable battery in constant use has a normal distribution, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = lifetime of the batteries.
µ = mean lifetime
σ = standard deviation
From the information given,
µ = 516 hours
σ = 20 hours
Looking at the normal distribution table, the z score corresponding to ninety percent approximately is 1.28
Therefore,
1.28 = (x - 516)/20
Cross multiplying by 20, it becomes
20 × 1.28 = x - 516
25.6 = x - 516
x = 516 + 25.6
x = 541.6
Therefore, Ninety percent of all batteries have a lifetime less than
541.60 hours
Answer:
The distance between point N and S is 8 units.
Step-by-step explanation:
count the distance from the x-values:
- from -2 to 6
OR
plot them on a graph and count the units that are between them.
