Answer:There are two right triangles. You need to find the opposite side (the height) of each of them. The difference between the two is the height of the blade, x.
You know the adjacent, 440, and you are looking for the opposite, so you need to use tan for both.
tan (30) = y / 440
y = 440 * tan (30) = 254.034...
tan (38.8) = z / 440
y = 440 * tan (38.8) = 353.769.--
353.8 - 254.0 = 99.8 = 100 feet.
Step-by-step explanation:
3x - 15 = 105
3x = 120
x = 40
3(40) - 15 + y + 24 = 180
120 - 15 + y + 24 = 180
129 + y = 180
y = 51

Answer:
C
Step-by-step explanation:
Equation : -1x² - 14x + 2 = 0General Formula : b2-4ac=0a=-1, b= -14, c= 2Put the Value in General FormD = (-14)2 - 4 x -1 x 2D = 196--8D = 204
and the polynomial has 2 real roots
