The benchmark angles are angles that are used as references like- 30 degrees, 45 degrees, 60 degrees, etc.
The closest angles to given rotation angles are:
A- 40- closest to the multiple of 45 degrees.
B- 140- closest to the multiple of 45 degrees (135 degree).
C- 170- closest to the multiple of 30 degrees (closest to 180 degrees which is multiple of both 30 and 45 degrees).
D- 220 -closest to the multiple of 30 degrees (210 degree).
E- 250- closest to the multiple of 30 degrees (240 degree).
F- 310- closest to the multiple of 45 degrees (315 degree).
You would have to move terms which will bring you to 14.4 x - 19.2 = 19.2 - 4.8x the you would combine like terms then you would get 19.2x= 38.4 then you divide both sides by 19.2 and get 2 as your answer.
The ‘e’ represent how many zeros there are .....

Answer:
y = -29/19 and x = -44/19
Step-by-step explanation:
3x + 2y = -10 multiply by -2 ⇔ -6x - 4y = 20
2x - 5y = 3 multiply by 3 ⇔ <u> 6x - 15y = 9 </u>
Add the two equation -19y = 29
y = -29/19
Use equation one and solve for x
3x + 2(-29/19) = -10
3x - 58/19 = -10
3x = -10 + 58/19
3x = -190/19 + 58/19
3x = (-190 + 58)/19
3x = -132/19
x = - 132/ 19 ÷3 
x = -44/19
Answer:
172.7 ft²
Step-by-step explanation:
Fencepost = Cylinder
Cylinder surface area : A = 2πrh + 2πr²
Cylinder surface area : A = 2 (3.14 × 0.5ft × 5ft) + 2 (3.14 × 0.5²ft) =
15.7 + 1.57 = 17.27 ft²
17.27 ft² × 10 = 172.7 ft²
