Answer: C, It stays the same.

Step-by-step explanation: If you simplify the ratio (the fraction) by canceling the t's, you get 2/1 or 2:1. This means that no matter the value of the variable t, the value of the expression will stay the same.

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

54. The triangles in the diagram below are congruent.
Reika [66]

Answer:

Angle N should be 64

Step-by-step explanation:

A triangle adds up to 180. So triangle JKL already has 60 towards 180. Triangle ONM already has 56 towards 180. So you have to find the other value needed in order to make 180. 56+60= 116 so we need to find the other angle to make 180. To do so just subtract 180-116 and that gives tou the answer 64 so that would be Angle N
