Line t. It cuts directly into the angle. Don’t get it confused with bisect because that comes directly from the angle and not just anywhere on it. Hope this helps

1/1

vlada-n [284]

1+2=3, 12 divided by 3=4 4x1=4, so there is 4 red marbles. 4x2=8 so there is 8 blue marbles. We can check this is true by adding 8+4 which =12.

blue=8
red=4

Find the value of x.

Alik [6]

Answer:

$x =15$

Step-by-step explanation:

In $\odot D,$ AB and AC are chords which are equidistant from the center of the circle.

$\therefore Chord \: AB \cong Chord\: AC$

$\therefore m \widehat {AB} = m\widehat {AC}$

(Equal chords intercept equal arcs)

$\because m \widehat {AB} = (10x-23)\degree$

$\therefore m \widehat {AC} = (10x-23)\degree$

$m \widehat {AB} +m \widehat {AC} +106\degree = 360\degree$

(Arc sum postulate of a circle)

$(10x-23)\degree + (10x-23)\degree= 360\degree- 106\degree$

$2(10x-23)\degree = 254\degree$

$(10x-23)\degree = 127\degree$

$10x-23 = 127$

$10x = 127+23$

$10x = 150$

$x = \frac {150}{10}$

$x =15$

Reduce ratio 49:21 to lowest form

mafiozo [28]

$\bf 49:21\implies \cfrac{49}{21}\implies \cfrac{7\cdot 7}{3\cdot 7}\implies \cfrac{7}{3}\cdot \cfrac{7}{7}\implies \cfrac{7}{3}\cdot 1\implies \cfrac{7}{3}\implies 7:3$
