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:
they differ when they are in different sign's but Will be same if the division sign change and the forward number will be reciprocal so it will be the same
Answer:
sqrt(3)/2
Step-by-step explanation:
sinAcosB+cosAsinB = sin(A+B)
sin(22)cos(38)+cos(22)sin(38)
= sin(22+38) = sin(60)
= sqrt(3)/2
