I assume you mean, that an angle and two sides are known.
A formula that can be used for irregular triangles is the cosine rule.
'b' and 'c' must be sides that are beside the angle 'A' (angle opposite 'a').
It is x squared you have to subtract
Answer:
In order to change a rational number to a decimal, we just convert the number into the form of a fraction. We then divide the numerator with the denominator and find out the exact value of the division.
5 units over
with a scale factor of .5
What this is asking is how do you turn the one shape into the other. The first answer is how many spaces apart they are. In this case the smaller rectangle EHGF was 5 units (or squares over... Also note that the fact that the larger rectangle is higher doesn't matter because the space is reduced when it is shrunk). The second answer was talking about how much smaller it was. This is identified by counting the sides. rectangle EHGF had sides 1 unit (square) and 2.5 units (squares) long this is half or .5 of the larger ABCD's 2 units (squares) and 5 units (squares).
