Help me to find AC please

Mathematics
1 answer:
spin [16.1K]3 years ago
4 0

Answer:

see explanation

Step-by-step explanation:

Since the triangle is right use cosine or sine to solve for AC

note cos30° = \frac{\sqrt{3} }{2}, thus

cos30° =  \frac{adjacent}{hypotenuse} = \frac{AC}{BC}  =\frac{AC}{\frac{10}{3} } and

\frac{AC}{\frac{10}{3} } = \frac{\sqrt{3} }{2}, that is

\frac{3x}{10} = \frac{\sqrt{3} }{2} ( cross- multiply )

6x = 10\sqrt{3} ( divide both sides by 6 )

x = AC = \frac{10}{6} \sqrt{3} = \frac{5}{3} \sqrt{3}

Mo travels 30 miles in 45
Burka [1]

Answer:

38.4 miles per hour

Step-by-step explanation:

30 miles in 45 minutes

18 miles in 30 minutes

Average speed =   total distance / total time

                          =    (30+18) / ( 45 min + 30 min)

                          = 48 miles / ( 1.25 hr ) = 38.4 miles per hour

ABCD is a parallelogram. If AB =3x+4, and CD =4x-1, find the length of AB
RSB [31]
If AB = CD, then 3x+4 is equal to 4x-1

3x + 4 = 4x - 1
Add one to both sides to cancel out.
3x + 5 = 4x
Subtract 3x from both sides to cancel out.
5 = x

Now, substitute the 5 in place of the x in the equation for AB (3x+4)

3(5) + 4
15 + 4
19

Final Answer: B) 19
