Use the triangle to answer the question.Find the value of x. Round to the nearest degree.

AlexFokin [52]

Given:

base = 16

hypotenus = 21

$\cos \theta=\frac{base}{hypotenus}$

Angle = x

$\begin{gathered} \cos x=\frac{16}{21} \\ \cos x=0.76 \\ x=\cos ^{-1}(0.76) \\ x\approx40 \end{gathered}$

The value of x is 40 degree.

Solve for X $1200 is 10% of X

iogann1982 [59]

Answer:

X = 12000

Step-by-step explanation:

1200 is 10% of X

Writing in equation form, we get,

$1200 = \frac{10}{100} * X\\X = \frac{1200*100}{10}\\X = 12000$

How do you solve 0.8=6-2.5x

photoshop1234 [79]

X=2.08

To solve you need to first get x by itself. To do that you want to subtract 6 from both sides (get 6 away from x and put on other side) which will leave you with -5.2=-2.5x next isolate x by dividing -2.5 on both sides to then get 2.08=x

Could you help me figure out the left/right facesortop/bottom faces

jolli1 [7]

Explanation

The question requires that we figure out the sides that represent the top/bottom faces and the left/right faces.

We are given the plan of the aluminum sheet

The top, bottom, left and right faces are shown below

The dimension for the top and bottom is

$1.5ft\times5ft=7.5ft^2$

Since they are two

Therefore the total area for the top and bottom will be

$2\times7.5ft^2=15ft^2$

For the left and right faces, the dimensions are

The dimensions of the left and right faces will be

$\text{1}.25ft\times5ft=6.25ft^2$

Since they are two, then

The area will be

$6.25ft^2\times2=12.5ft^2$
