Sin(pi/4) = 1/sqrt(2)
csc(pi/4) = sqrt(2)
csc^2(pi/4) = 2

Ali drove 754 miles in 13 hours.
Rudiy27

Answer:

464 miles

Step-by-step explanation:

Divide.

She drove 754 miles in 13 hours. So that means her rate(her speed) was 58 mph.(754/13= 58)

Multiply.

So if she were to drive at the same rate for only 8 hours that would be 464 miles.( 58 x 8= 464)

#1: what is the value of V<br><br> Can anyone help me with these questions?
PIT_PIT [208]

Answer:

v = 15

Step-by-step explanation:

Sum of the angles inside a triangle add up to 180

angle 1 = 31

angle 2 = 4v+44

angle 3 = 180 - 9v

since 9v is the supplement to the angle inside the triangle then

some angle + 9v  has to equal 180

which we can solve for the that angle to be 180 - 9v

therefore

180- 9v + 31+ 4v+ 44 = 180

Simplify it down by combining like terms

255 -5v = 180

subtract 255 to both sides

-5v = -75

divide by -5

v = 15
