Answer:
Your answer would be:
D = 53 d.
First off notice how the top left and bottom right angels are obtuse angels (larger than 90 degrees). The top right and bottom left angels are acute (less than 90 degrees).
We will focus on the acute angels to finger out the problem. The value D that we are trying out must add to 26 degrees to equal the value of the other cute angle, 79 degrees (top right corner).
We can solve with the following equations:
26 degrees + D degrees = 79 degrees
79 d. - 26 d. = D d(egrees)
Summary:
79 d. - 26 d. = 53 d.
In conclusion, the value of angel D would equal 53 degrees.
D = 53 degrees
Have a great rest of your day
