Answer:
GH = 22.5
Step-by-step explanation:
Since ∆ABC is similar to ∆FGH, therefore:
Plug in the values
AC = 12 cm
FH = 18 cm
BC = 15 cm
GH = ??
Plug in the values
.
Cross multiply
12*GH = 270
Divide both sides by 12
GH = 22.5
Use the formula for volume=LWH
750 I believe multiply the digits all together
Answer:
11
Step-by-step explanation:
the greatest common factor is 8 so you know you have to have 8 rows, divide all of those number by 8 and add the answers
Answer:
sin∅= - √6/3
Step-by-step explanation:
Trigonometric function cos is even function which mean:
cos (-∅) = cos ∅
Trigonometric function sin is odd function which mean:
sin (-∅) = - sin∅ => sin∅ < 0
The basic trigonometric equation reads in this case with angle marked ∅:
sin²∅ + cos²∅ = 1 => sin²∅ = 1 - cos²∅ => sin²∅ = 1 - ( √3/3 )² =>
sin²∅ = 1 - (3/9) => sin²∅ = 1 - (1/3) = (3/3) - (1/3) = 2/3 => sin∅ = - √(2/3) =>
sin∅ = - √2/√3 => sin∅ = - √6/3
God with you!!!
