Answer:
D. The sum is a rational expression.
Step-by-step explanation:
the given expression is a/b +c/d
so in the question it is given that b and d are non zero values
a/b is rational number and c/d is a rational number
so if both are rational number , so we know that the sum of rational number is also a rational number.
The right option is D. The sum is a rational expression
Answer:
with what?
Step-by-step explanation:
??
The area of a triangle =

× the length of one side × the length of another side × sin(the angle between
these two sides). For our example, because we know one side = 10 and the angle is 30° we will use these in our formula for 'easyness'.
Area of triangle =

where <em>A</em> is the angle in-between the two sides <span>b</span> and <span>c</span><em>.</em> (b=10, A = 30°, c=???)
We need to find <em>c</em> on your diagram and then we can use the formula above. We can use the sine rule to find the length of side <em>c</em>.

We know the angles in a triangle add up to 180° which means angle <em>C</em> must equal 180° - 45° - 30° = 105° so

side <em>c</em> = 13.66 so

Area = 34 square units (to nearest square unit)
