Answer:

0.2793

Step-by-step explanation:

We are asked to convert 16° to radians.

#We know that 1° is equal to π/180 or 0.01745rad.

To convert any angle degrees to radians, we multiply it by π/180:

=16\textdegree \times \pi/180\\\\=\frac{4\pi}{45} \ \ rad  \ or  0.2793\ rad

Hence, the radians equivalent of 16° is 0.2793

Step-by-step explanation:

You need to use the law of sine for both of them

the law of sine is as follows:

\frac{a}{\sin(A)}=\frac{b}{\sin(B)}=\frac{c}{\sin(C)}

Question 1:

\frac{15}{\sin(64)}=\frac{10}{\sin(y)}\\y=36.81233927

Question 2:

Let x= AB

Start by solving for the missing angle, 53

\frac{8.4}{\sin(31)}=\frac{x}{\sin(53)}

x= 13.02532494

The remains of an ancient ball court include a rectangular playing alley with a perimeter of about 18m. The length of the alley
mariarad [96]

Given:

Perimeter = 18 m

The formula for the perimeter of a rectangle is:

P=2l+2w

Where:

l = lenght

w = width

In this case, we have that:

l = 2w

Therefore, we substitute the values in the formula:

\begin{gathered} P=2l+2w \\ 18=2(2w)+2w \end{gathered}

And solve for w:

\begin{gathered} 18=4w+2w \\ 18=6w \\ \frac{18}{6}=\frac{6w}{6} \\ w=3 \end{gathered}

For the length:

l=2w=2(3)=6

Answer:

The width is 3 m

The length is 6 m
