2) 12:88=3:22 (simplest answer)
Answer:
x= 90 degree
y= 43 degree
Step-by-step explanation:
We have been given an isosceles triangle being two sides equal AB and AC
By the property of isosceles triangle
The sides which are equal will have same base angle
Hence, ∠ABC=∠ACB=
We know that sum of angles of triangle is
∠ABC+ ∠ACB+∠BAC= (1)
Since, ∠BAC is the bisector so, ∠BAD and ∠DAC are equal which is
Now, substituting the values in (1) we get:
Now, we will consider ΔABD to find x
,∠ADB=∠ABD=
Now, Apply the sum of angles of triangle is we get:

Answer: The answer is 0.7265.
Step-by-step explanation: I don't know how to explain. Put the tangent of pi / 5 into your calculator.
You get 0.726542528...
But you round to 4 decimal places.
This rounds to 0.7265.
