Find the value for β that makes cosβ = sin15 true.

Gemiola [76]

Answer:

Step-by-step explanation:

This is an equation for which you need to solve for the value of the missing angle beta.

$cos\beta =sin(15)$

sin(15) has a decimal answer that you will find on your calculator. Finding that value makes this equation then

cosβ = .2588190451

Now use the 2nd button and then the cos button to find the angle that has a cos of that decimal. When you hit 2nd then cos, you should see this on your screen:

cos⁻¹ (

After that open parenthesis, enter you decimal then hit the enter button to find the angle. You should get 75, which is Choice B.

Can anyone help me with this with easy tricks

Lorico [155]

Answer:

1,120 cm³

Step-by-step explanation:

Hello!

<u>Think about it this way:</u> There is a rectangular prism, with lengths of 20cm, 12cm, and 10cm, and another rectangular prism cut out of it with lengths, of 8cm, 8cm, and 20cm.

<h3>Larger rectangular prism</h3>

Volume = L * W * H

V = 20cm * 12cm * 10cm
V = 2,400cm³

<h3>Cut-Out Rectangular Prism</h3>

V = L * W * H

V = 8cm * 8cm * 20cm

V = 1,280cm³

Subtract:

2,400cm³ - 1,280cm³

1,120cm³

The total volume is 1,120cm³
