Mathematics
1 answer:
otez555 [7]3 years ago
3 0

Answer:

69 degree

Step-by-step explanation:

Using cosine formula again :))

So we have

BC^2 = AB^2 + AC^2 - 2*AB*AC*cosA

BC^2 = 32^2 + 28^2 -2*28*32*cos56

BC = 28.3884 cm

So B:

AC^2 = AB^2 + BC^2 - 2*AB*BC*cosB

CosB=0.3559

B=69.14 degree

777dan777 [17]
Perpendicular = opposite sign and reciprocal slope
Slope would be 3
Y = 3x + b, plug in point
9 = 3(5) + b, b = -6
Solution: y = 3x - 6

The freezing point of water is 32°F. When water is at or below this temperature, it is in solid form. Which statements are true
mamaluj [8]

Answer:

The number 32 is part of the solution set

The circle on the graph is closed

The arrow on the graph points to the left

Step-by-step explanation:

The number 32 is part of the solution because it said that water freezes at 32 degrees when it is at or below 32

The circle on the graph is closed because 32 is part of the answer , when the solution is showed then the circle is closed.

Last but not least the arrow on the graph points left because water freezes when it is at 32 or below 32 degrees, so when it points left the numbers become lower.

Hope this helped! :)
