Out of 28 kids there is one that isnt 12
so 27 kids are 12 years old
1 isnt
concluding that, that 6th grade might be 11
so 1 out of 28
1:28
Answer:
∅ = 30°
Step-by-step explanation:
given data
side 1 = 6 inches
side 2 =
inches
to find out
angle opposite the leg that is 6 inches long
solution
we will use pythagoras theorem that is express as
hypotenuse² = perpendicular² + base² .......................1
put here value and we get hypotenuse
hypotenuse² = 6² + ( )²
solve it we get
hypotenuse² = 144
hypotenuse = 12 inches
now we apply here sin∅ that is
sin∅ =
................2
put here value and we get
put here value and we get
sin∅ =
∅ =
solve it we get
∅ = 30°
2 x 14 = 28
28/13 rounds off to 2.15.
9 * 1/3 is 3.
2.15 - 3 = -0.85
Or -17/20.
