First row, the answer on the left , -5 3/4 - 4 2/3
Answer:
4 16 2.000
5 25 2.236
6 36 2.449
7 49 2.646
Step-by-step explanation:
Align the horizontal edge of the protractor with the base of the triangle. Place the center point of the protractor on the vertex of the angle. Follow the side of the triangle until it reaches the angle measurement mark. Note the measurement.
This is an octagon, which has 8 sides.
the angle of rotation is 360/8 = 45°
The unit normal for the given plane is <5,2,-1>.
The equation of the plane parallel to the given plane passing through (5,5,4) is therefore
5(x-5)+2(y-5)-1(z-4)=0
simplify =>
5x+2y-z=25+10-4=31
Answer: the plane through (5,5,4) parallel to 5x+2y-z=-6 is 5x+2y-z=31
