Given:
A right angle triangle with angles 45, 45, 90 degrees.
Hypotenuse of the triangle = mm
Base of the triangle = t
To find:
The value of t.
Solution:
In a right angle triangle,
Using this trigonometric ratio in the given triangle, we get
Therefore, the value of t is 7 millimetres.
Yes, they are both functions.
By taking a common denominator, we can find out that the simplified expression of the given expression is .
The given expression is -
---- (1)
We have to simplify the expression.
From equation (1), we have the given expression as -
Establishing common denominator , we have
Combining the numerator and common denominator, we have
Thus, the simplified expression of the given expression is which is obtained by taking a common denominator.
