The angle of B is 
Explanation:
It is given that
and 
To determine the
, let us use the law of sine formula.
Thus, we have,

Substituting the values in the formula, we have,

Multiplying both sides by 3,we get,

Simplifying and dividing, we get,

Multiplying both sides by
, we get,

Thus, 
Hence, The angle of B is 
Answer:
7kg:1kg=7:1 itself
Because 7 and 1 has one '1' as a common factor, so they can't be simplified
Where is the <span> graph we cant answer without it sorry</span>
Answer:
the vertex is (-7,-90)
the focus is ( -7, -359/4)= (-7,-89.75)
semi-axis length; 1/4=0.25
focal parameter: 1/2=0.5
eccentricity;1
directrix: y=-361/4
