Question

What is the measure of angle 3

Answer 1

Answer:

<3=31

Step-by-step explanation:

since opposite angle are equal angle 3 and  the angle on the left side of 118 have to be equal. And since there are 180 degrees in a triangle,180-118=62,  62/2= 31 so  angle 3 is 31

hope this helps

Answer 2

ANSWER

$\angle3 = 31\degree$

EXPLANATION

The adjacent angles of a parallelogram are supplementary.

The angle adjacent to 118° is

$180 \degree - 118 = 62 \degree$

Since the diagonals bisect corner angles,

we divide the adjacent angle into two to obtain;

$\angle3 = \frac{62 \degree}{2} = 31\degree$
