Question

Find measure of angle d A. 122 degrees B. 61 degrees C. 238 degrees D. Not enough information

Answer 1

It is B. 61 degrees, you can estimate.

Answer 2

Answer:

B. $61^{\circ}$

Step-by-step explanation:

We have been given an image of a quadrilateral. We are asked to find the measure of angle D.

We can see that angle A and angle D are equal, so we can represent measure of both angles as $2D$.

We know that all the interior angles of a quadrilateral are equal to 360 degrees, so we can set an equation as:

$2D+98^{\circ}+140^{\circ}=360^{\circ}$

$2D+238^{\circ}=360^{\circ}$

$2D+238^{\circ}-238^{\circ}=360^{\circ}-238^{\circ}$

$2D=122^{\circ}$

$\frac{2D}{2}=\frac{122^{\circ}}{2}$

$D=61^{\circ}$

Therefore, the measure of angle D is 61 degrees and option B is the correct choice.
