Answer: You shouldn't hate trig.
Step-by-step explanation:
SinΘ= opposite/hypotenuse
SinΘ=y/x
Sin(16) = 9/x
x = 9/Sin(16)
x= 32.7 cm
Answer: 10/63
Step-by-step explanation: To multiply fractions, you just time's the top numbers and then the bottom numbers by themselves.
For instance: 2 x 5 = 10
9 x 7 = 63
and there is your answer.
:)
1 and 2 i can't answer without proper data.
3. x+2x+2x+6 = 86
5x+6 = 86
-6 -6
5x = 80
x = 16
Side one: x is 16
Side two: 2x is 2(16) = 32
Side three: 2x+6 is 38
