Answer 1

Answer:

1. x => 128°

98° + 104° + 120° + 90° + x = 540°

412 + x = 540

x = 540 - 412

x = 128°

2. y = 115°

101° + 126° + 135° + 147° + 96° + y = 720°

605° + y = 720

y = 720 - 605

y = 115°

3. 3M + 2M + M+2 + 100° = 360°

6M + 102 = 360

6M = 360 - 102

M = 258/6

M = 43

3M = 3×43 = 129°

2M = 2×43 = 86°

M+2 = 43 + 2 = 45°

4. x = 125°

100° + 97° + x + 38° = 360°

235 + x = 360

x = 360 - 235

x = 125°
