Answer:
The value of
is
.
Step-by-step explanation:
The given equation is <em>
.</em>

The inverse of the function is found by adjusting the equation such that, expressing x in terms of f(x).


now, <em>x =
and f(x) be x.</em>
Thus, 
Now, inserting value of x as 12,
<em>
</em>
<em>
</em>
The answer should be 103 :-)
Since the sum of the angles of a triangle = 180°
Then (2x)º + (x + 60)º + (3x)º = 180°
(6x)° + 60° = 180°
(6x)° = 180° - 60°
x = 120° ÷ 6
∴ x = 20
Answer:
4:1 ratio is the answer
Step-by-step explanation:
Answer:
(2) a rotation by
about the intersection of the lines creating the vertical angles.
Step-by-step explanation:
Rigid motion are a set of transformation procedure to change the dimension, orientation or size of a given figure or shape. It involves rotation, translation, reflection and dilation.
Vertical angles are formed when two straight lines intersect to form angles. But two opposite angles called vertical angles are equal. To prove that vertical angles are equal; a rotation by
about the intersection of the lines creating the vertical angles is required.
