Answer:
1. True
2. HGK
3. 17⁰
Explanation:
1. All angles in a triangle need to add up to 180. The right angle is a given 90⁰ so the other two angles need to add up to 90⁰ to equal 180⁰. Angle C corresponds to Angle K so Angle H corresponds to Angle E. So add Angle C and H together and it sums up to 90⁰ so it is true.
2. HGK; you match it up with the markings inside the triangle
3. Same logic with number 1 but you subtract 90 from 73 to find Angle K.
I hope this helps!!!
