Can use right angle angle trigonometry as this is a right triangle

sine is opposite over hypotenuse

sin 60 = BC/AB because opposite to 60 is BC and the hypotenuse is AB.

rearrange for AB

sin 60 = BC/AB
AB sin 60 = BC
AB = BC / sin 60

we are given that BC = 15 in

AB = 15 / sin60
AB = 17.321 in (calculator

can use tangent of 60 degrees to find AC
tangent is opposite over adjacent so

tan(60) = BC / AC
AC tan 60 = BC
AC = BC / tan 60
AC = 15 / tan 60
AC = 8.660 in

Surface area of a trash can plz show work

ollegr [7]

Answer:

Step-by-step explanation:

So first we need to find the area of the trash can so here is the math:

The formula:

A=LxW

Replace the letters with numbers:

8=2x4

So the area is 8 feet now we can create an equation to solve how much money it would take to make the trash can:

8x0.79=$6.32

It would take $6.32 to make the trash can

A bowl of fruit is on the table. It contains 5 apples, 2 oranges, and 2 bananas. Christian and Aaron come home from school and r

Sholpan [36]

The probability that both grab oranges would be = $\frac{1}{36}$

Step-by-step explanation:

Given,

A bowl contains,

Apples = a = 5

Oranges = o = 2

bananas = b = 2

Total fruits in bowl = x = a + o + b = 5 + 2 + 2 = 9

Now, Christian and Aaron come home from school and randomly grab one fruit each.

The probability of first selecting orange would be = $\frac{o}{b} = \frac{2}{9}$

Now, the oranges left would be 2 - 1 = 1

and total fruits would be = 9 - 1 = 8

Hence, the probability of selecting second orange would be = $\frac{1}{8}$

Therefore, the probability that both grab oranges would be = $\frac{1}{8} * \frac{2}{9} = \frac{1}{36}$

Answer:

x^2 + 3x -1

Step-by-step explanation:

f(x) = 3x-2

g(x) = x^2+1

(f+g)(x) = 3x-2+x^2+1

Combine like terms

= x^2 + 3x -1

Convert 118 to radian measure.<br><br> Round your answer to the nearest hundredth.

dangina [55]

Answer:

2.06 rad

Step-by-step explanation:

To change degree measure to radian measure

radians = degrees × $\frac{\pi }{180}$ , then

radians = 118 × $\frac{\pi }{180}$

= $\frac{118(\pi )}{180}$ ≈ 2.06 rad ( to the nearest hundredth )
