Answer:

60

Step-by-step explanation:

to find w:

sin(44) = w/30

w = 30sin(44)

w = 20.8 to 1 decimal place

to find x;

cos(x) = 20.8/45

x = cos^{-1}(20.8/45)

x = 62.46940334

x = 60

Answer:

a = 22

b = 31

c = 13

Step-by-step explanation:

The sum is the same in each row, column, and diagonal.

One of the diagonals is already complete.  The sum is:

16 + 25 + 34 = 75

So the first row adds up to 75:

a + 37 + 16 = 75

a = 22

The second row adds up to 75:

19 + 25 + b = 75

b = 31

And the third row adds up to 75:

34 + c + 28 = 75

c = 13

We can check our answer by finding the sum of each column and the other diagonal.

22 + 19 + 34 = 75

37 + 25 + 13 = 75

16 + 31 + 28 = 75

22 + 25 + 28 = 75

What is the slope of the line that passes through points (2,-3) and (5,1)
Ivenika [448]

Find the difference in the y-coordinates: -3 - 1 = -4

Find the difference in the x-coordinates in the same order: 2 - 5 = -3

Divide the difference in y by the difference in x: slope = (-4)/(-3)

Reduce the fraction: slope = 4/3
