8 because it goes from 1s 10s 100s so 8 is the answer
Answer:
Step-by-step explanation:
<B=90-47=43
AB/BC=sin 47
BC=AB/sin 47=18/0.731=24.6 nearly
AC/AB=Tan 43
AC=18 tan 43=16.8 nearly
Answer:
y = 7 sqrt(2)
Step-by-step explanation:
Since this is a triangle, we can use trig functions
sin theta = opp/ hyp
sin 45 = 7/y
y sin 45 = 7
y = 7/ sin 45
y = 7 / (1/sqrt(2) )
y = 7 sqrt(2)
Answer:
y = 
x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (0, 4)
m = 
=
Note the line crosses the y- axis at (0, 4) ⇒ c = 4
y = x + 4 ← equation of line
A=LW, and we are told that L=W+10
Using L=W+10 in A=LW you have:
A=(W+10)W
A=W^2+10W
W^2+10W=880, we are told that A=880 so
W^2+10W=880 now we can complete the square...
W^2+10W+25=905
(W+5)^2=905
W+5=±√905
W=-5±√905, since W>0
W=-5+√905 and since L=W+10
L=5+√905
W=-5+√905 ft and L=5+√905 ft
If we want an approximation:
W≈25.08 ft and L≈35.08 ft (both dimensions to the nearest hundredth)
