You multiply by the conjugate to both the denominator and numerator.
After that you can simplify by canceling the 4 and then you are able to simplify the (h) as well.
y is part of a right angle on line AB
a right angle = 90 degrees
90-47 = 43 degrees
y = 43 degrees
a straight line = 180 degrees
180-47 = 133 degrees
x = 133 degrees
Answer:
Step-by-step explanation:
Find the volume first.
V= l * w * h
l = 2 cm
w = 3 cm
h = 1 cm
V = 2 * 3 * 1 = 6 cm^3
Density = mass / volume
Density = 420 grams / 6 cm^3
Density = 70 grams / cc^3
Kind of large. Check your givens.
