Answer:
1. a = 63⁰
2. b = 30⁰
3. c = 25⁰
4. d = 57⁰, e = 90⁰, f = 49⁰
5. g = 53⁰
Step-by-step explanation:
1-3. Right angle is always 90⁰.
1. 90-27
2. 90/3
3. 90-40= 50/2 = 25
4. not sure but the sum of three angles in up and down should be 180⁰.
d = 82+41 = 123⁰
d = 180 - 123 = 57⁰
f + 41 is a right angle so 90-41 = 49⁰
f = 49⁰
e = 41 + 49(f) = 90 = 180 - 90 = 90⁰
5. the same in number 4, 74 + 53 = 127 = 180 - 127 = 53°
