To find d in the figure, we need to use the fact that the angles of a triangle add up to 180 degrees.
Since angle c is 70 degrees and angle b is 50 degrees, we can subtract their sum from 180 to find angle d:
d = 180 - (70 + 50)
d = 180 - 120
d = 60
Therefore, angle d is 60 degrees.

60 is the wrong answer
Apologies for the mistake.
As mentioned before, the sum of angles in a triangle is always 180 degrees.
We are given that angle c is 70 degrees and angle b is 50 degrees.
To find angle d, we need to subtract the sum of angles c and b from 180:
d = 180 - (70 + 50)
d = 180 - 120
d = 60
Therefore, angle d is 60 degrees.
