Note
Tangents from an external point to a circle's circumference are equal.
So
WZ = WX
WZ = 5a + 12
WX = 7a + 5
7a + 5 = 5a + 12 Subtract 5 from both sides.
7a = 5a + 12 - 5
7a = 5a + 7 Subtract 5a from both sides.
7a - 5a = 7
2a = 7 Divide by 2
a = 7/2
a = 3.5
Answer:
32
Step-by-step explanation:
32 × 1 = 32
8 × 4 = 32
Therefore, the LCM is 32
Teesha is in French Club:
=> 10 freshman
=>12 sophomores
=>15 juniors
=> 30 seniors in the club.
The advisor is going to randomly choose one ofthe members of the club to be a guide for an important visitor.
Out of 4 groups, only 1 will be selected.
=> 10 freshman + 12 sophomores +15 juniors + <span>30 seniors = 67 students
</span>=> 67 / 4 = 16.75
OR close to
=> 15/67
