Answer:
P = 30 degrees, PQ = 6.93, PN = 8
Step-by-step explanation:
For the angle, just subtract the angles you already know from 180, so 180 - 90 - 60= P. P = 30 degrees.
For PQ, use tan60 = x/4, or 4tan(60), which equals 6.93.
For PN, use cos60 = 4/x, or 4/cos60, which equals 8.
Hopefully this helps- let me know if you have any questions!
Answer:
(x-7) (x+4)
Step-by-step explanation:
x^2 - 3x - 28
What two numbers multiply to -28 and add to -3
-7*4 = -28
-7+4 = -3
(x-7) (x+4)
They would be perpendicular. hope this helps.
Answer:
a is not a linear equation
Answer:
Area = 112cm^2
Step-by-step explanation:
Area = (a + b)*h / 2
M = (a + b) / 2
14 = (a + b) /
2*14 = a + b
28 = a + b
Area = 28*8 / 2
Area = 112 cm^2
