The expression sin 57° is equal to

ValentinkaMS [17]

Answer:

$cos(33^{\circ})$

Step-by-step explanation:

Given

$sin(57^{\circ})$

Required

Determine an equivalent expression

In trigonometry:

$sin(\theta)= cos(90^{\circ} - \theta)$

In $sin(57^{\circ})$

$\theta=57^{\circ}$

Substitute $57^{\circ}$ for $\theta$

in $sin(\theta)= cos(90^{\circ} - \theta)$

$sin(57^{\circ})= cos(90^{\circ} - 57^{\circ})$

$sin(57^{\circ})= cos(33^{\circ})$

Hence, the equivalent expression is: $cos(33^{\circ})$

Paula’s painting has a perimeter of 1.47 meters. She wants to put ribbon around the edge. If the ribbon comes in pieces that are

julia-pushkina [17]

Answer:

Step-by-step explanation:

Each centimeter is equal to .01 meters

Or 100 centimeters = 1 meter

So if we convert Paula’s painting perimeter of 1.47 meters to centimeters, it would be 147 centimeters.

Now, since each ribbon comes in pieces that are each 25cm, we know are left with an easy division problem 147 divided by 25 or 5.88.

Since she needs the least amount of ribbons that it would take to wrap around the perimeter of the painting, we know it would be 6 because 6x25 = 150cm.
