Answer:
65
Step-by-step explanation:
70 - 60 = 10
10 / 2 = 5
Thus 65
We are given
we know that
so, we get
opposite =7
adjacent=24
now, we can find hypotenuse
now, we can draw triangle and then switch vertices accordingly
we can find cos(B) using second triangle
In second triangle:
adjacent=7
hypotenuse =25
so, we get
................Answer
Let us assume the length of a side of the square floor = x feet
Area of the square floor as given in the question = 320 square feet
Then
x^2 = 320
x^2 = (17.89)^2
Then
x = 17.89
= 18 feet approx
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the second option or option "B".
i say C. -5, -2, 1, 4, 7 is your answer for question 1.
and for question 2 i think is E. -6, -4, -2, 0, 2.
