please ,I will mark as brainliest if it's a nice and correct and with step by step.
of the question given​

Answer 1

Step-by-step explanation:

Hope it helps you can directly find a and b without finding x term also...

Answer 2

Answer:

a = 70 degree, b = 40 degree

Step-by-step explanation:

First Method(Long):-

We know that alternate interior angles are equal.

So, angle Y = angle a

Therefore, angle a = 70 degree.

We also know that sum of interior angles in a triangle is 180 degree

So, angle Y + angle Z + angle X = 180 degree

= 70 + 40 + X = 180 degree

Therefore, angle X = 180 - 110 = 70 degree.

Now, angle a, angle b and angle X form a straight angle.

So, angle a + angle b + angle X = 180 degree

= 70 + b + 70 = 180 degree

Therefore, angle b = 180 - 140 = 40 degree

__________________________________

There is even one more method which is very simple.

Second Method(Short):-

We know that alternate interior angles are equal.

So, angle Y = angle a

Therefore, angle a = 70 degree.

In the same way, even angle Z = angle b

Therefore, angle b = 40 degree.

Hope this answer is helpful!
