Answer: 355.49
Step by Step:
82.14+9.77+31.35+41.25=164.51
520-164.51=355.49
Okay so triangle DEA = 71 degrees
And angle DEB = 90 degrees (right angle)
90 - 71 = 19 degrees
Angle EBA = 90 degrees (right angle)
That leaves the 90 degrees + 19 degrees = 109 degrees
There’s 180 degrees in a triangle so
180 - 109 = 71 degrees
By the base is regular they mean it as all sides are 4m long
- 3.4 > - 4.2 is the only correct statement
> means larger than
< means smaller than
A negative number which closer to 0 than an other negative number, is larger. Therefore - 3.4 is larger than - 4.2, and therefore - 3.4 > - 4.2
The greater the absolute value of the slope, the steeper the line.
Therefore, slope of -3 represents the steepest line.
