Answer:

<em>tan 19° = 0.3443</em>

Step-by-step explanation:

<u>Value Of Trigonometric Functions</u>

The value of the tangent of 19° cannot be expressed in exact form, that it, as a function of radicals or known constants as pi.

We need to use a calculator, computer, or similar technology to find the required value. We use a scientific calculator to get:

tan 19° = 0.3443

Answer:

Grapes 12 lbs

Apples 20 lbs

Oranges 6 lbs

Cantaloupe 15 lbs

Peaches 15 lbs.

Step-by-step explanation:

Sammy has bought 12 lbs of Grapes.

Now, weight ration of Apples to Grapes is 5 : 3

Therefore, he bought Apples of $\frac{12 \times 5}{3} =20$ lbs

The wight ration of Grapes to Oranges is 4 : 2

Therefore, he bought Oranges of $\frac{12 \times 2}{4} =6$ lbs

Again, the weight ratio of Cantaloupe to Apples is 3 : 4

Therefore, he bought Cantaloupe of $\frac{20 \times 3}{4} =15$ lbs

Finally the weight ratio of Oranges to Peaches is 2 : 5

Therefore, he bought Peaches of $\frac{6 \times 5}{2} =15$ lbs
