How do you solve for X and round the nearest tenth​

Mathematics

Advocard [28]3 years ago

Answer:

x = 7.3

Step-by-step explanation:

When solving for missing sides using angles, use trig functions.  

We have the angle 63° to use.  

We are given the hypotenuse of the triangle, as well as the side adjacent to the angle, so we can use the cos function.

Cos T = (adjacent side)/(hypotenuse)

Here we know 'T' and the hypotenuse, so plug them in and solve

Cos 63° = x/16

  (16)Cos 63° = x    (multiply both sides by 16 to isolate 'x')

      7.263847996 = x           (use your calculator to solve the left side)

      7.3 = x   (rounded to the nearest 10th)

Can someone help me with this question​
Doss [256]

Answer:

Step-by-step explanation:

For any prism or cylinder for that matter, you can find the volume by multiplying the area of the base times the height.  So this problem just becomes simple algebra.

B * h = V

25 * h = 80

h = 80/25

h = 3.2

If you don't get why it's the area of the base let me know and I can try to explain it.
