Answer:
For number 1, the answer is 90°, 55°, and 35°
Step-by-step explanation:
A triangle always equals 180 so you have to subtract the other angles to find the third one. Since you already know that one angle is 35° and the other is 90° you can do 180-90-35 and that equals 55 so those three are your three angle measures
For the show your work part of #1 write:
180°-90°-35°=55°
