7 0

Answer:

C) 128

Step-by-step explanation:

Sum of all three angles of triangle = 180

Let the third angle be 'x'

x + 12 + 40 = 180

     x + 52 = 180

             x = 180 - 52

            x = 128

A commercial package contains thirty-six 200-mg tablets of ibuprofen. How many kilograms of ibuprofen were
PIT_PIT [208]

Answer: 0.0072 kilogram

Step-by-step explanation:

Given : The mass of one tablet of ibuprofen =200  mg

Then, the mass of 36 tablets of ibuprofen =36\times200  mg

i.e. the mass of 36 tablets of ibuprofen =7200  mg

We know that 1 kilogram = 1000 grams

and 1 gram = 1000 milligram

Then, 1 kilogram = 1000,000 milligrams

Then, \text{1 mg}=\dfrac{1}{1000,000}\text{ kg}

Now,  \text{7200 mg}=\dfrac{7200}{1000,000}=0.0072\text{ kg}

Hence, A commercial package contains 0.0072 kilogram of ibuprofen.

In the 30-60-90 triangle below, side s has a length of _ and side q has a length of _.
gregori [183]

Answer: F

Step-by-step explanation:

For a 30-60-90 triangle, we know that the hypotenuse is 2x. Since we know the hypotenuse is 10, we can solve for x.

2x=10

x=5

Now that we know x is 5, we can use this to solve for s and q. The side across from 30° is just x. Since we know x, s is 5.

The side across from 60° is x√3. Since we know what x is, we can just plug in. q is 5√3.

If in triangle ABC, a=5, b=6 and c=8, then cos A is...
s2008m [1.1K]

In a triangle, the nomenclature is that a variable side a is opposite of the angle A. we can use the cosine law to determine the value of cosine A. 
a2 = b2 + c2 -2bc cos a25 = 36 + 64 - 2*6*8 * cos acos a = 25/32
