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.

-<br> (<br> -<br> 7.4–1.1)–(2.1–8.1)
SashulF [63]

Answer:

0.3

Step-by-step explanation:

(7.4-1.1) - (2.1-8.1)

Lets start with (7.4-1.1)

Step 1:

(7.4-1.1) =6.3 (All you do is subtract 7.4-1.1 and it gives you 6.3)

Step 2: Lets do (2.1-8.1)

(2.1-8.1)= -6 (2.1 minus 8.1 gives you -6 because 2.1 is smaller than 8.1 so it will give you a negative)

Step 3: Subtract

6.3-6

So your answer would be 0.3

Hope that helped :)

Use a number line to compare the numbers. Which shows the correct symbol to compare the numbers? 1.2 1 1/5
Leno4ka [110]

For this case we must compare the following expressions:

1.2\\1 \frac {1} {5}

We convert the mixed number to a fraction:

1 \frac {1} {5} = \frac {5 * 1 + 1} {5} = \frac {5 + 1} {5} = \frac {6} {5} = 1.2

So, we have to compare:

1.2 and 1.2

It is observed that the expressions are equal, so we have the sign of equality "=":

1.2 = 1.2

Answer:

1.2 = 1.2
