It seems like you are asking for the measurement of angle 1, but I don't have the figure you mentioned. To provide an answer, I'd need more information about the context of angle 1, such as the relationships between the angles or any given measurements that relate to it.
If you have specific details, like the types of angles involved (complementary, supplementary, etc.), or measurements of other angles or sides, please provide them, and I'll do my best to help you solve for the measure of angle 1!
