Top, right because the numbers are increasing by the same amount (2 in this case).
Answer:
A
Step-by-step explanation:
90-49=41
41-3=38
49+(38+3)=90
Answer:
59.1 for the mean
Step-by-step explanation:
You add all the numbers together and divde it by the amount of numbers there are.
1.75 hours, add them up and divide by two and you get your answer
The acute angles of a right triangle are complementary, so
α + β = 90
(5x/3 +20) + (2x/3) + 14) = 90 . . . . . . substitute given values
7x/3 +34 = 90 . . . . . . . . . . . . . . . . . . . collect terms
7x/3 = 56 . . . . . . . . . . . . . . . . . . . . . . . subtract 34
x = (3/7)*56 = 24 . . . . . . . . . . . . . . . . . multiply by 3/7
Then the value of α is ...
α = 5*24/3 +20 = 60
