Answer:
5.543 miles
Step-by-step explanation:
The law of cosines can help with this. It relates side "c" of a triangle to the other two sides (a, b) and the angle between them (C).
c² = a² +b² -2ab·cos(C)
c² = 3² + 3² -2·3·3·cos(135°) = 18(1 -cos(135°)) ≈ 30.7279
c ≈ √30.7279 ≈ 5.543 . . . . miles
Answer:
B,C,D
Step-by-step explanation:
B= solve your equation step-by-step.
y
1.75
=4
Step 1: Multiply both sides by 1.75.
y
1.75
=4
(
y
1.75
)*(1.75)=(4)*(1.75)
y=7
----------------------------------------------------------
C= solve your equation step-by-step.
5y=35
Step 1: Divide both sides by 5.
=
Thus y=7
---------------------------------------------------------
D= solve your equation step-by-step.
22+y=29
Step 1: Simplify both sides of the equation.
y+22=29
Step 2: Subtract 22 from both sides.
y+22−22=29−22
y=7
