By definition, the arc length is given by:
 s = R * teta
 Where,
 Radio
 Teta: arc angle measured in radians.
 We have then that the length of the arc in this case is:
 s = (7.9) * (180-66.4)) * (pi / 180)
 s = 15.7 cm
 Answer:
 The length of the AD arc is:
 s = 15.7 cm

PLEASE HELP<br>what is the value of x? enter your answer in the box​
Mashcka [7]

Answer: 3

For this question, we will use the angle bisector theorem.

Angle Bisector Theorem: In geometry, the angle bisector theorem is concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle. It equates their relative lengths to the relative lengths of the other two sides of the triangle.

Now let's place it according to a general formula.

x/2.25 = 4/3

x= 4/3 * 2.25

x= 3

There you go! now you know the answer and the way to do it! Brainliest pweasee if the answer is correct and helpful!

How do i find the perimeter and area?
Contact [7]

First, we need to find the base. To do so, we will need to use the Pythagorean Theorem on one of the smaller triangles to solve for its unknown side. Then, we can double the base of the one to find the base of the whole.

Pythagorean Theorem: a^2 + b^2 = c^2

(12)^2 + b^2 = (16)^2

144 + b^2 = 256

b^2 = 112

b = \sqrt{112}

b = 4\sqrt{7}

total base = 2 x 4\sqrt{7} = 8\sqrt{7}

Second, we can find the area. The formula for the area of a triangle is A = 1/2 x base x height.

A = 1/2 x 8\sqrt{7} x 12

A = 4\sqrt{7} x 12

A = 48\sqrt{7} units^2

Third, we can find the perimeter. The perimeter is the sum of all of the exterior sides.

P = 16 + 16 + 8\sqrt{7}

P = 32 + 8\sqrt{7} units

Hope this helps!! :)

What is the sum of f and 6
Inga [223]
The sum of f and 6 is simply f+6.
It is like this because f is a variable and we do not know its value.
