This is the formula you would use to calculate how many tiles you would need.
# of tiles you need = Total square footage ÷ square footage of each tile
Total square footage: 69x69 = 4761 square feet
Square footage of each tile = 2x2 = 4 square feet
# of tiles you need = 4761 ÷ 4 = 1190.25
You will need 1190.25 tiles.
To find the area of this triangle, we may use Heron's formula:
A = sqrt ((s)(s - a)(s - b)(s - c))
where s is the semi - perimeter, a, b, and c are the measure of the sides.
s = (a + b + c) / 2 = (10 + 10 + 16) / 2 = 18
Substituting this to the equation for area,
A = sqrt ((18)(18 - 10)(18 - 10)(18 - 16))
A = 48 units²

Answer:
The equation of the line passing through the point (1,-4) and making an angle of 135º will be:
Step-by-step explanation:
Given the point (1, -4)
Given that the line makes an angle of 135º.
so
Slope = m = tan 135º = -1
Using the point-slope form of the line equation
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = -1 and the point (1,-4)
subtract 4 from both sides
simplify
Therefore, the equation of the line passing through the point (1,-4) and making an angle of 135º will be:
The correct answer is A. The total points Shelly earned
