In plane ABC the measure of angle A equals 42° the measure of angle B is five times the measure of angle C find the measure of a
krok68 [10]

Step-by-step explanation:

I think what is meant in the triangle ABC we have the three angles.

the sum of all angles in a triangle is airways 180 degrees.

so,

180 = A + B + C

180 = 42 + B + C

now, we know also that

B = 5×C

so, we can use that above

180 = 42 + 5×C + C

138 = 6×C

C = 138/6 = 23 degrees

B = 5×C = 5×23 = 115 degrees

How much chromium-51 will be left after 7 months?
Makovka662 [10]

Answer:

It seems there's more information in you question that you haven't posted.

7 months = 7 * (365/12) = 213 days

The half-life of chromium 51 is 27.7 days.

After 7 months, chromium 51 will have undergone 7.69 half-lives.

To solve for the ending amount we'll use the formula:

Ending Amount = Beginning Amount / 2^n where 'n' = # of half-lives

We'll say the beginning amount =1

Ending Amount = 1 / 2^7.69

Ending Amount = 0.0048426082

Basicaly if you started with 1 gram of chromium 51, after 7 months you would have 0.0048426082 grams.

In triangle ABC, cos A =
nikitadnepr [17]

The other expression that has a value of \frac{7}{25} is A) sin B.

Step-by-step explanation:

Step 1:

sin\theta = \frac{oppositeside}{hypotenuse} , cos\theta = \frac{adjacentside}{hypotenuse} , tan \theta = \frac{opposite side}{adjacent side} .

For angle B, the opposite side measures 7 units, the adjacent side measures 24 units and the hypotenuse measures 25 units.

sinB= \frac{oppositeside}{hypotenuse} = \frac{7}{25} , tan B = \frac{opposite side}{adjacent side}  = \frac{7}{24} , cosB = \frac{adjacentside}{hypotenuse}  = \frac{24}{25}.

Step 2:

For angle A, the opposite side measures 24 units, the adjacent side measures 7 units and the hypotenuse measures 25 units.

tan A = \frac{opposite side}{adjacent side}  = \frac{24}{25} .

Step 3:

tan C cannot be determined as C is the right angle. The opposite side and hypotenuse of the triangle would be the same.

So sin B also has a value of \frac{7}{25}. This is option A.
