Answer: ∠A=
Step-by-step explanation:
Since we have given that
CD bisects m∠ACB,
⇒ m∠ACD= m∠DCB =x (say)
And, AB=BC, m∠BEC=90°, and m∠DCE=42°
So,
m∠CAD=m∠ACD
In ΔDCE,
Now, in ΔACD,
Hence , ∠A=

Option 2 is the answer.
Step-by-step explanation:
To find the equation for we will fist write the function in the form of equation.
y = √x +3
√x = y - 3
x = (y - 3)² = y² - 6y + 9
Now we will replace y as x to write inverse of function f(x).
We will rewrite the equation in the form of function.
= x² - 6x + 9 ≅ (x - 3)²
So the answer is = (x - 3)²
