Answer:

please see explanations

Step-by-step explanation:

For the first question,

Sum of angles in a triangle equal

180°

3x + 4x + 2x = 180

9x = 180°

Dividing bothsides by 9

9x/9 = 180/9

x = 20

The measure of the interior angles are :

3x = 3(20) = 60

4x = 4( 20) = 80

2x = 2(20) = 40

For the second question,

Let's find x first.

Angles on a straight line equal 180°.

x + 92 = 180

x = 180 - 92 = 88°

To find A note that:

Exterior angle equal sum of opposite interior angles.

A = 88° + 43°

A = 131°
