Question

Find the measure of angle 1

Answer 1

38°

Explanation:

Angles in a triangle add up to 180° and opposite angles are equal, therefore 180°-104°=76°

76°÷2=38°

I think this is correct :)

Answer 2

The correct answer is <1 = 38°

Explanation:

From the figure we can see a parallelogram.

Opposite angles of a parallelogram are equal.

To find the measure of <1

From the figure we get <1 + <2 = <3 + <4

<1 = <2

<1 + <2 + <3 + <4 = 360 - (2 * 104)

= 360 - 208 = 152

<1 + <2 = 152/2 = 76°

<1 = <2 = 76/2 = 38°

Therefore measure of <1 = 38°
