Answer 2

`\huge\boxed{110}`

Explanation:

We can solve for m∠A by using angle relationships to find it's value.

It's important to note first: m∠BCD and m∠BCA are supplementary. This means that their angle measurements will add up to 180°.

We already know m∠BCD so we can find m∠BCA by subtracting it's measurement from 180.

`180-130=50`

So m∠A = 50 degrees.

Now, we also know that all angles in a triangle add up to 180°. Since we already know the measures of ∠B and m∠BCA, we can find the measure of m∠A by adding up what we know and subtracting from 180.

`50+20=70\\\\180-70=110`

So m∠A is 110 degrees.

Hope this helped!
