Step-by-step explanation:
1. vertically opposite angles are the same
b = 42
360 - (42 + 42)
360 - 84 = 276
276 ÷ 2 = 138
c = 138
2. angles in a triangle sum to 180
right angles = 90
180 - (90 + 62)
180 - 152 = 28
angle S = 28
3. 1st question no, unless one angle is given a number. angles are the same vertically opposite so the other 2 angles are also vertically opposite but angle is different size but by adding the 2 different angles, make them supplementary as they sum to 180. 2nd question yes. you could have 4 right angles.

Answer:
probability the student plays both instruments is [ 
]
<h2>
<u>
Explanation</u>
:</h2>
students who play both instruments = total students - flute players - piano players - students who play neither instruments
students who play both instruments
→ 31 - 4 - 14 - 7
→ 6 students play both instruments.
probability:
