Answer : 58 square units.

Tip : break the shape down into shapes you can easily find the area of.

I found the area of the two squares on the bottom
They are identical and are both 2 units tall and two units long giving, giving an area of 4, and since there are two of them you can multiply the are by two giving you 8
Next found the area of the remaining shape which is just a rectangle that excludes the two bottom squares which is 10 units long and 5 units tall multiplying to 50
50+8=58

180° &lt; x &lt; 270°, what is the value of tan-1(0.577)?
Allisa [31]
Think:  "Find <span>tan-1(0.577)" means "Find the ANGLE in Quadrant III whose tangent is 0.577.  Because the angle is in QIII, both the opp side and the adj side are negative.  Here you have four answer choices.  The correct answer MUST be within the interval 180 and 270 degrees.  Only one of the given answer choices satisfies that criterion.  Which one is it?
