Answer 1

1: 98

2: 82

3: 98

4: 82

Explanation:

So 2 is 82deg then the opposite is also 82 so 4 is 82deg

Then 82+82 = 164deg, and we remain with 360deg-164deg which is = 196.

Since the other two angles will be equal (they are opposite each other) we can decide 196/2 = 98

So 3 and 1 are 98deg

Answer 2

Step

<2 and <4 are vertically opposite. They are equal

<2 = 82 Given

<4 = 82 Vertically opposite to a given

<3 = 180 - 82 <3 and <4 are supplementary. They are on the same straight line.

<3 = 98

<1 = 98 Vertically opposite angles are equal.
