Length: 1/5 = 2/10
Width: 1/2 = 5/10
Perimeter = 2 (Length + Width)
= 2 (2/10 + 5/10)
= 2 ( 7/10)
= 14/10
= 1 and 4/10 = A. 1 and 2/5
Plug in -7 for x in the equation...
f(x) = 3 - 2( - 7 )
f(x) = 3 + 14
f(x) = 17
Answer:
x = 14.7
Step-by-step explanation:
Use Law of Sines.
7/sin20=x/sin46
cross multiply
7sin46=xsin20
divide both sides by sin20 to isolate x
x = 7sin46/sin20
x = 14.72
