First you connect the lines by making a triangle. Then you get the value of one side (4) and you square it. (4 squared= 16). You also do the same with another side (3 squared= 9). And then you add them and square root the number to get the answer. (5)

Factor 1/4 out of 1/4x -13/4

sweet-ann [11.9K]

$\bf \frac{1}{4}(x-13)\qquad 
\begin{cases}
\frac{1}{4}\cdot x\implies &\frac{1}{4}x\\\\
\frac{1}{4}\cdot 13\implies &\frac{13}{4}
\end{cases}$

Help me as soo as possible please, the M in Mbc stands for “angle”

JulijaS [17]

Answer:

Step-by-step explanation:

Given is a picture of circle with angle

BOC =7x-11

Also angle of arc BC = angle BOC = 3x+53

Since both are the same equate the two

$7x-11=3x+534x=64x=16$

Now substitute this x value in any one of 3x+53 or 7x-11

Angle COB = angle BOC = 3x+53

= 48+53 = 101 degrees

-------------------------

To find length of arc

Central angle = 101

Hence arc lengh = $\frac{101}{360} 2(\pi r)\\=2\frac{101}{360}(3.14)(5)\\=8.81$
