This corresponds to answer C. 122 students play an instrument.
A triangle with 9 meters,12 meters ,and 15 meters is a triangle because the two sides lower numbers sides add to get a bigger number the the thrid side so I would be a right triangle
x=0
it’s a step by step equation
if you want i can give you the work
Step-by-step explanation:
x²+x-12=0
by factorization
x²-3x+4x-12=0
taking common
x(x-3)+4(x-3)
(x+4)(x-3)
x= -4. x=3
Answer:
3)
x = 5.3
4)
<A = 22.6°
<B = 67.4°
Step-by-step explanation:
Tan(A) = 5/12
<A = 22.6°
Tan(B) = 12/5
<B = 67.4°
Or you can find <B = 90 - <A) = 90° - 22.6° = 67.4°
3)
tan(24) = x / 12
x = 12 * tan(24)
x = 12 * 0.4452
x = 5.3
