Answer:
The answer is complementary ⇒ last answer
Step-by-step explanation:
In any right triangle there are two acute angles sum of them is 90°
∵ The two angles will be complementary if there sum is 90°
∵ cosФ = sinβ
∵ cosФ = sin(90 - Ф)
∴ β = 90 - Ф
∴ β + Ф = 90
∴ β and Ф are complementary
Answer:
Since x = -2
x satisfies the condition of x < 1
Hence, the output will be x + 3
-2 + 3
=1

Answer:
By arranging the data set.
Week one has the highest range of 55 minutes
Step-by-step explanation:
Range = highest data minus lowest data.
So lers arrange our data and determine the range of each week
Week 1
Sunday 85, monday 35, Tuesday 50, Wednesday 60, Thursday 30, Friday 35, Saturday 50
Acsending order
=30, 35, 35,50,50 ,60,85
Range = 85-30 = 55
Week 2
Sunday 55 ,Monday 50, Tuesday 45 Wednesday 45 ,Thursday 40 ,Friday 30 ,Saturday 50
Acsending order
= 30,40,45,45,50,50,55,
Range=55-30 = 25
Week one has the highest range of 55 minutes
