<em><u>Explanation</u></em><em> </em><em>:</em>
The line DF is parallel to OB, therefore Angle x = Angle y.
( because, they for corresponding angle pair which are equal. )
And the angle made by an arc at center is always double the angle made by the same arc at its boundary, hence
<span> x =(-12-√-432)/18=(-2-2i√<span> 3 </span>)/3= -0.6667-1.1547i</span><span> x =(-12+√-432)/18=(-2+2i√<span> 3 </span>)/3= -0.6667+1.1547i</span><span> x = 4/3 = 1.333</span>
Answer:
4
Step-by-step explanation:
2 cubes on each 6 × 8 face will have one surface painted. The sides of dimension 4 cm do not have enough width to have any cubes with only one face painted.
Hence, there are a total of 4 cubes with one face painted.
Answer:
15
Step-by-step explanation:
√36 = 6
√256 = 16
√49 = 7
√36 + √256 - √49
= 6 + 16 - 7
= 22 - 7
= 15
